Abstract

An unsymmetric pyrazolate ligand with different chelating side arms in the 3 and 5 positions of the heterocycle {3-[(EtSCHCH) NCH]-5-[(EtNCHCH) NCH] CNH (HL)} and its symmetrical analogue {3, 5-[(EtSCHCH) NCH] CNH (HL)} have been prepared. Upon reaction with NiCl· 6HO they afforded dinuclear complexes [NiLCl] 2 and [NiLCl]
