Abstract
A newly prepared ligand, N,N-bis(pyrazol-1-ylmethyl)benzylamine (L) reacted with metal ions to form [FeLCl3], [NiL(NCS)2(MeOH)], [MLX2] (M = CoII, CuII or ZnII, X = Cl-, Br- or NCS-) and [(CuLI)2]. The crystallographically determined structures of [CoLCl2] and [CoL(NCS)2] reveal the co-ordination sphere of cobalt(II) to be intermediate between distorted tetrahedral and trigonal bipyramidal. In [NiL(NCS)2(MeOH)] the co-ordination sphere of nickel(II) ion is distorted octahedral while that of copper(II) in [CuLCl2] is distorted square pyramidal. The complex [(CuLI)2] displays distorted tetrahedral geometry around copper(I), and [ZnLBr2] shows distorted tetrahedral geometry around zinc(II).
