Halogeno-complexes of cobalt(I) and nickel(I) with 1,1,1-tris(diphenylphosphinomethyl)ethane
Abstract
The terdentate ligand 1,1,1-tris(diphenylphosphinomethyl)ethane (I) forms cobalt- and nickel-(I) complexes of general formula MLX (X = Cl, Br, or I). Spectral and magnetic data on the compounds are presented. They are non-electrolytes, are all isomorphous (X-rays) with the analogous Cu1 complexes, and probably have a pseudotetrahedral structure.
