 Abstract    zweikerniger Vanadium(V)-Komplex mit (r/1)-und (/x-772:?72)-gebundenen Hydrazido(2-)-Liganden A D inuclear V anadium (V) C om plex w ith (r/1)-and (^ -//2://2)-Bonded H ydrazido(2-) L igands The title complex was obtained by reaction of guanidinium dioxodipicolinatovanadate(V) and N-methyl-N-phenylhydrazine. According to the single crystal structure analysis the dinuclear anion [(/i-PhN NH)(/t-O CH 3){(M ePhN N (dipic)V)}2]~ with sevenfold coordinated metal cen­ ters contains two types of hydrazido ligands. The ligand [MePhNN]: ~ is terminally bonded, and the VNN unit is linear with extensive electron delocalisation. The V-N and N-N bond lengths are 167.9(5) and 131.9(6) pm, respectively. The bonding of the bridging ligand is of the hitherto unknown fi-rf'.rf type, with V-N and N-N bond lengths of 202.5(5) and 136.5(5) pm, respectively. The V (N 2)V moiety is not planar. The compound was also characterized by H and 1V NMR spectroscopy.
