Synthesis and Structure of a Copper(II) Complex of N,N' -Bis(di- para -tolylphosphinoylmethyl)-1,8-diamino- 3,6-dioxaoctane

A copper(II) complex of N,N' -bis(di- para -tolylphosphinoylmethyl)-1,8-diamino-3,6-dioxaoctane was synthesized and its crystal structure was established. The inner coordination sphere of the complex is a strongly distorted trigonal bipyramid. Coordination involves the phosphoryl oxygen atoms, nitrogen atoms, and ether oxygen atom, and one axial position is occupied by a water molecule.
