摘要
Reaction of NH4ReO4 with excess 2-hydrazinopyrimidine in methanol yields [Re(eta(1)-NNC4H3N2H)(eta(2)-HNNC4H3N2)Cl-3] (1) Attempts to recrystallize 1 by slow diffusion of methanol into DMF after 8 months produced black crystals of [Re(HNNC4H3N2)(NNC4H3N2)(OCH3)(2)](4) (2). The structure of 2 consists of isolated tetranuclear clusters, constructed from {Re(eta(2)-HNNC4H3N2)(eta(1)-NNC4H3N2)(OCH3)(2)} units linked through the beta-nitrogen of the chelating organodiazene ligand of adjacent units into a box-like aggregate.
