The reactions of the cis-dioxorhenium(VII)-catecholate complex [(CH{sub 3}CH{sub 2}){sub 4}N][ReO{sub 2}(O{sub 2}C{sub 6}H{sub 4}){sub 2}] (1) with either monosubstituted organohydrazines (C{sub 6}H{sub 5}NHNH{sub 2}; 4-BrC{sub 6}H{sub 4}NHNH{sub 2}) or 1,1 disubstituted organohydrazines (Ph{sub 2-}NNH{sub 2}) yield the cis-bis(diazenido) core complexes [(CH{sub 3}CH{sub 2}){sub 4}N][Re(NNR){sub 2}(O{sub 2}C{sub 6}H{sub 4}){sub 2}] (5, R = C{sub 6}H{sub 5}; 6, R = 4-BrC{sub 6}H{sub 4}) and the cis-bis(hydrazido) core species [(CH{sub 3}CH{sub 2}){sub 4}N][Re(NNPh{sub 2}){sub 2}(O{sub 2}C36H{sub 4}){sub 2}(O{sub 2}C36H{sub 4}){sub 2}] (7). Elution of 5 in a 3:1 mixture of toluene/methanol on a column of silica gel resulted in cation exchange to give Na[Re(NNPh){sub 2}-(O{sub 2}C{sub 6}H{sub 4}){sub 2}]{center_dot}CH{sub 3}CN (8) as a one-dimensional polymer ([Na(CH{sub 3}CN)]{sup +}[Re(NNPh){sub 2}(O{sub 2}C{sub 6}H{sub 4}){sub 2}]{sup {minus}}){sub 2}.
