The novel ferrocenylcarbaldehyde benzoylhydrazone ligand H(Fe)L-1 has been prepared and its reaction with fac-[ReBr(CO)(3)(CH3CN)(2)] in chloroform gave [ReBr(CO)(3){H(Fe)L-1}] in good yield. Both compounds have been characterized by elemental analysis, MS, IR, UV-Vis and H-1 NMR spectroscopic methods and their structures elucidated by X-ray diffraction. Four crystallographically independent molecules of H(Fe)L-1 are associated by N1-H and N-2 or O atoms of a neighbouring ligand or methanol molecules to give chains running along the b axis. The hydrazide group is O,N-bidentate and affords a five-membered chelate ring in the rhenium complex. The geometry around the metal is fac-octahedral. The intermolecular associations based on C(Fc)-(HO)-O-... hydrogen bonds are also discussed. (c) 2006 Elsevier Ltd. All rights reserved.
