摘要

Reaction of a 1 : 1 : 1 molar ratio of NiCl2, NaN3 and H2L, a tetradentate ligand N-(2-pyridyl) methyl)- N, N- bis(2'-hydroxy-3',5'-dimethylbenzyl) amine in methanol in presence of Et3N results in a turquoise precipitate, which affords deep green crystals of [Ni-2(HL)(2)(N-3)(2)] center dot 1.5CH(2)Cl(2) ( 1) and [Ni-2(HL)(2)(N-3)(2)] center dot H2O (2) upon crystallization from CH2Cl2 - MeOH or THF - MeOH, respectively. Both complexes reveal distorted octahedral NiN4O2 coordination environments around the Ni(II) centers with bis(mu- 1,1-azido) bridging ligands. Complex 1 displays an unprecedented small Ni - N - Ni bridge angle of 90.4 degrees, whereas 2 contains the said angle of av. 98.7 degrees lying in the usual range observed for other comparable structures. The variable-temperature magnetic susceptibility together with the variable-field, variable-temperature (VTVH) magnetization measurements discern different ground states of S-t = 0 for 1 and S-t = 2 for 2. The magnetic behaviours of these compounds are discussed in the context of the known bis(end-on azido) bridging dinickel( II) complexes.
