Synthesis, and crystal structure of a novel tetra-nuclear Nickel (Ⅱ) complex derived from pyridine-2-carboxaldehyde bearing an intramolecular acetato bridge

摘要

Recently, intense interest has been focused on studies of cubane-like poly-nuclear complexes due to their relevance to multi-electron transfer centers systems, and to their interesting properties .Tetranuclear cubane-like Ni complexes have been extensively investigated since the pioneering work of Andrew and Blake . A number of cubane-like complexes involving bridging ome, or alkoxo have beenpreviously reported. To understand the active role the transition metal ion played in the process of organicsynthesis and interestine molecular nrooerties.
