Es werden neue Erkenntnisse über Borphosphat und Borophosphate der Haupt- und Nebengruppenmetalle vorgestellt. Neben Hydrothermalsynthesen und Feststoffreationen, die üblicherweise zur Synthese von Borophosphaten angewendet werden, haben insbesondere die solvothermalen Experimente mit Alkoholen bzw. Alkohol-Wasser-Mischungen zu neuen Ergebnissen geführt. Es wurden neue Borophosphate und Borat-Phosphate in den Systemen MxOy–B2O3–P2O5(–H2O) (M = K+, Rb+, Mg2+, Sc3+, Pr3+, Sm3+, In3+) dargestellt, weitere Verbindungen enthalten neben Mg2+ weitere Kationen der Haupt- und Nebengruppenmetalle (Ca, Sr, Ba, Mn, Fe, Co, Zn). Darüberhinaus gelang die Darstellung bislang unbekannter Scandium- und Lanthanphosphate(III) sowie von sauren Alkalimetall-Scandiumphosphaten(V). Aus Synthesen in Gegenwart von Ethylendiamin und Diazabizyklooktan wurden ferner zwei neue templatierte Scandiumphosphate mit porösen Gerüststrukturen erhalten. Die Kristallstrukturen aller Verbindungem wurden rötgenographisch anhand von Einkristallaufnahmen oder Pulverdaten aufgeklärt. Die Charakterisierung der Präparate erfolgte mit Röntgenpulverdiffraktometrie, EDX- und Elementaranalysen sowie durch Schwingungsspektroskopie und thermische Stabilitätsuntersuchungen. Zur Klassifizierung von (Metallo)borophosphaten wird eine Struktursystematik vorgeschlagen, welche Borophosphate und Metalloborophosphate entsprechend ihrer anionischen Teilstrukturen hierarchisch klassifiziert und in Analogie zur Terminologie der Silikate (nach Liebau) beschreibt. In Anlehnung an bestehende Konzepte für Boratminerale geht das Klassifizierungsschema dabei von einfachen Oligomeren aus. In einer struktursystematischen Übersicht wurden alle bis dato bekannten (Metallo)Borophosphate hierarchisch klassifiziert und sind in einer Übersicht vorgestellt. Beobachtete Verknüpfungsregeln und der Einfluss der Zusammensetzung B:P auf die Dimensionalität und die Verknüpfungsmuster der anionischen Teilstruktur werden diskutiert.

The new borophosphates described here were synthesized under mild hydrothermal conditions (170 oC or 220 oC). Powder and single crystal X-ray diffraction were employed to determine and refine the crystal structures. DTA-TG methods were used to analyze the thermal stability. High temperature powder X-ray diffraction (HT-XRD) was applied to study the thermal behavior of products and identify the intermediate phase during the decomposition. Chemical analyses were performed to quantitatively determine the chemical composition. Magnetic properties of the compounds were investigated. 19F MAS NMR was used to check the number of fluorine positions in the crystal structure. The following compounds were prepared and characterized: (C2H10N2)[BPO4F2](C6H14N2){Zn[ZnB2P4O15(OH)2]¡P(C6H13N2)Cl} (zndabcocl) (C3H12N2){Mn[B2P3O12(OH)]} (DAP-Mn) and (C4H12N2){Mn[B2P3O12(OH)]} (PIP-Mn) (C3H12N2){FeIII6(H2O)4[B4P8O32(OH)8]}(C3H12N2)2{VIII2VIV3B2P8O38H8} (dapvbpo) K3[B5PO10(OH)3](C2H10N2)[BPO4F2] is the first fluorine-substituted borophosphate and the first borophosphate with crystal structure closely related to the pyroxene type structure. Unbranched zweier single chain {[BPO4F2]2?} represents a new type of borophosphate partial structure. zndabcoclrepresents the first organo-templated zincoborophosphate. The structure contains diaza-bicyclo[2.2.2]-octane (DABCO) which acts in its diprotonated form (H2DABCO)2+ as a pure template and in its monoprotonated form (HDABCO)+ as a ligand to Zn-positions at the borders of ribbons to complete structural motif. This compound is also the first example containing a quaternary Zn-tetrahedron (ZnO2NCl), and can formally be described as an adduct of (C6H14N2)Zn[ZnB2P4O15(OH)2] with diaza-bicyclo[2.2.2]octane-hydrochloride. The thermal behavior of zndabcocl has been studied by HT-XRD and DTA-TG in the temperature range 25?600 oC. The new phase occurring during the decomposition has been identified as HT-NH4[ZnBP2O8].DAP-Mnand PIP-Mn contain identical framework interconnections but difference in the shape of resulting channels, which are due to the different shape of organic templates. The crystal structures are built from the same building units: loop-branched single chains are connected via MnO6-octahedra resulting in a 3-D structure with intersecting channel systems running along [100], [011] and [01], respectively. The different shape of the template controls the shape of the channels, especially channels running along [100], resulting in dramatic shape-differences. The linear (H2DAP)2+ ions make the channels more elongated, while the cyclic (H2PIP)2+ ions give rise to more regular shaped channels. The flexibility of frameworks may be due to the more flexible coordination of Mn-atoms (octahedron and square pyramid).(C3H12N2){FeIII6(H2O)4[B4P8O32(OH)8]} is a new borophosphate with 3-D framework structure, a large size of 10-ring channel (778 ¡Ñ 867 pm2) is occupied by organic templates. The magnetic susceptibility measurements show it to exhibit antiferromagnetic susceptibility at low temperature (TN ?l 14K).dapvbpois the first mixed-valency vanadium borophosphate with a new structure type. Its structure can be considered as an ?intergrowth? of puckered vanadium(III) borophosphate layer (VIIIBPO-layer) and planar vanadium(IV) phosphate layers (VIVPO-layer) stacked and interconnected alternately along [001], which results in a new and unusual building motif. The corner sharing trimers of vanadium octahedra are observed for the first time in vanadium borophosphates. K3[B5PO10(OH)3] has a double unit cell of a twin crystal structure having the same chemical formula. The double b-axis solves the disorder problem of two oxygen positions coordinated to phosphorous. It represents a much more reasonable structure determination.
