Complexes of rhenium with benzoylazo and related ligands. Crystal and molecular structures of the “green chelate” benzoylazo complex [ReCl2(PPh3)2(NNCOC6H4-p-Cl)](Nα,O), of the analogous 1-azophthalazine chelate complex [ReCl2(PPh3)2(NNC8H5N2)](Nα,N1), and of the cis-dichloro organodiazenido complexes of the type [ReCl2(PPh3)2(NNR)L] (L = NCCH3, NH3 and C5H5N). A comparison to the structure of the trans- dichloro dimethylformamide derivative [ReCl2(PPh3)2(NNCO2CH3)(Me2NCHO)]. The structural characterization of the mixed hydrazido(1−) hydrazido(2−) complexes [ReCl2(PPh3)2(NNHR)(NHNHR′)], (R = R′ = −COC6H5; R = −COC6H5, R′ = −CO2CH3)
