Abstract

A series of N-(2-pyridyl) benzamides (1)–(11) and their nickel complexes,[N-(2-pyridyl) benzamide] dinickel (II) di-μ-bromide dibromide (12)–(16) and (aryl)[N-(2-pyridyl) benzamido](triphenylphosphine) nickel (II)(17)–(24), were synthesized and characterized. The single-crystal X-ray analysis revealed that 12 and 14 are binuclear nickel complexes bridged by bromine atoms and each nickel atom adopts a distorted trigonal bipyramidal ...
