Two compounds previously described as trichloro-bis(triphenylphosphine)rhenium(III) have been shown to be trichlorobis(triphenylphosphine oxide)rhenium(III) and oxotrichlorobis(triphenylphosphine)rhenium(V). Other phosphine complexes of Re(III) and Re(II) prepared in a similar manner to the latter have been shown to be com-pounds of Re(V). A new arsine complex of Re(V) and other arsine and arsine oxide complexes of rhenium(III) have been prepared. A triphenylphosphine complex of Re(II) has been prepared. Previously reported cyanide complexes of Re(VI) and Re(V) have been confirmed, although the purification procedure described for the latter causes hydrolysis of the compound. The supposed purple hydroxocyanide complex of Re(VII) has been shown to be the oxohydroxocyanide complex of_Re(V),- as have previously reported purple salts of the dioxotetracyanorhenate(V) have also been shown to be salts of this anion. The first transition metal-nitridocyanide complex has been prepared. A new method of preparing potassium dioxotetracyanorhenate(V) is described. It has been shown that the diagnostic region for M=0 infra-red stretching frequencies must be extended from 900 cm.-1 down to at least 780 cm.-1 where a linear 0=M=0 group exists in an octahedral complex. Stable phases Re205 and Re308 have been prepared by the oxidation of rhenium dioxide hydrate. The former is a mixture of Re03 and an unidentified oxide. The latter does not contain any Re03. Mixed phosphine 2:4-propanedione complexes of rhenium(V) and rhenium(III) have been prepared.
