Polynuclear nickel(<scp>II</scp>) complexes of N₄O₂- and N₄S₂-compartmental macrocycles: the structures of a Ni₄O₄cubane cluster and the binuclear nickel(<scp>II</scp>) complex of a benzenethiolate macrocycle

Abstract

The tetranuclear cluster [{Ni2(L1)(MeCO2)}2]2+(L1= the dianion of the condensation product of 1,3-diaminopropane and 2,6-diformyl-4-methylphenol) shows a distorted Ni4O4cubane structure consisting of octahedral nickel(II) centre; the structure of the dithiolate analogue [Ni2(L2)](PF6)2·2dmf (L2= the dianion of the condensation product of 1,3- diaminopropane and 2,6-diformyl-4-methylbenzenethiol;dmf = dimethylformamide)shows square-planar coordination at nickel(II).
