Os ácidos a-hidroxicarboxílicos utilizados foram os ácidos glicólico (C2H4O3), málico (C4H6O5), tartárico (C4H6O6) e mandélico (C8H8O3). Foram sintetizados treze compostos, sendo seis com o íon Mo(VI), quatro com o íon Ag(I) e três com o íon Pb(II). Além destes compostos, foram repreparados três compostos, (NH4)2[MoO2(C2H2O3)2]H2O, (NH4)2[MoO2(C8H6O3)2] e (NH4)2[MoO3(C4H4O6)] H2O. A partir destes três complexos foram obtidos óxidos (MoO3) com áreas superficiais entre 1,0 e 3,0 m2/g. Cinco compostos da série M2[MoO2(C2H2O3)2]nH2O, onde M = Li+, Na+, K+, Rb+ e Cs+; C2H2O3 2- = glicolato2- e n = 1 ou u, foram preparados a partir da adição de MoO3(s) em solução do sal alcalino desejado do ácido glicólico na proporção molar metal:ligante 1:2. Os compostos no estado sólido foram separados da solução por filtração após concentração e adição de etanol absoluto. Os compostos foram caracterizados por análise elementar, espectroscopia IV e difratometria de raios X. Foi realizado um estudo complementar de espectroscopia de RMN de 1H e de 13C para os compostos K2[MoO2(C2H2O3)2]H2O, K2[MoO2(C8H6O3)2] e K2[MoO3(C4H4O6)]H2O. Os compostos da série M2[MoO2(C2H2O3)2]nH2O são fotossensíveis à radiação UV, sendo o complexo K2[MoO2(C2H2O3)2]H2O, o que apresenta maior fotossensibilidade. O composto Na2[MoO2(C4H4O5)2]uH2O foi obtido a partir de MoO3 e ácido málico utilizando-se a metodologia descrita para os compostos da série M2[MoO2(C2H2O3)2]nH2O. O complexo obtido foi caracterizado por análise elementar, espectroscopia IV e difração de raios X.

Glycolic (C2H4O3), malic (C4H6O5), tartaric (C4H6O6) and mandelic (C8H8O3) acids were the a-hydroxycarboxilic acids used in this work. Thirteen complexes were obtained: six complexes with Mo(VI), four complexes with Ag(I) and three complexes with Pb(II). The complexes (NH4)2[MoO2(C2H2O3)2]H2O, (NH4)2[MoO2(C8H6O3)2] and (NH4)2[MoO3(C4H4O6)] H2O were prepared again in order to measure specific area of the respective oxides after calcination. These three compounds led to the formation of MoO3 with superficial area ranging from 1.0 to 3.0 m2/g. The compounds of the series M2[MoO2(C2H2O3)2]nH2O, where M = Li+, Na+, K+, Rb+ and Cs+, C2H2O3 2- = glicolate2- and n = 1 or u, were synthesized in aqueous medium by the reaction of the respective salt of the glycolic acid with molybdenum trioxide. Molar ratio of 1:2 metal:ligand was used. The solution was concentrated until the formation of a viscous product. The solid complexes were obtained by addition of ethanol. The complexes were characterized by elemental analysis (C, H and O), thermal analysis (TG/DTA), infrared spectroscopy and X-ray diffractometry (powder method). An additional study using nuclear magnetic resonance spectroscopy (1H and 13C) was performed with K2[MoO2(C2H2O3)2]H2O, K2[MoO2(C8H6O3)2] and K2[MoO3(C4H4O6)]H2O. These compounds showed to be photosensitive to the UV radiation. The complex K2[MoO2(C2H2O3)2]H2O was the most photosensitive. The complex Na2[MoO2(C4H4O5)2]uH2O was obtained from MoO3 with malic acid by the use of the same methodology of synthesis of the complexes of type M2[MoO2(C2H2O3)2]nH2O. This complex was characterized by elemental analysis, infrared spectroscopy and X-ray diffractometry... (Complete abstract, click electronic address below)

This thesis deals with use of the measuring system MAAS-1 for direct determination of vertical deviations at the points specified field. The main input data are geographical and astronomical coordinates of points. The aim of this thesis is to complete the processing of data measured in the locality.

My master´s thesis deals with use of astronomical levelling for creation of quasigeoid models. The basic input dates are componets of astronomical-geodetic deflections of the vertical in points, which are determined on AGNES and VEVEŘÍ nets. The dates are adjust for determination of relative quasigeoid. In literature [4], there is simplified solution for adjustment of this dates. The thesis looks for the most comprehensive solutions of adjustment without simplification. The solutions are compared.
