Synthesis and structural characterization of a dinuclear Cu(I) complex [Cu₂ (PXBDPA)Cl₂]

Abstract

A dinuclear Cu(l) complex of the composition [Cu₂(PXBDPA)Cl₂] (where PXBDPA = ɑ, ɑ’-bis(bis(2-(diphenylphosphino)ethyl)amino)-<em>p</em>-xylene) has been synthesized by the reaction of Cu(PPh₃)₃Cl with the ligand PXBDPA. The complex has been characterized on the basis of elemental analysis, ¹H, ¹³C and ³¹PNMR spectral data. The molecular geometry of the complex has been established by single crystal X-ray diffraction method which shows that the structure of the complex contains a centre of symmetry which is located at the centre of the <em>p-</em>xylyl ring so that the molecule is divided into two identical halves. The Cu(I) atom shows a trigonal planar geometry with ligation to two phosphorus atoms of the ligand and a chloride ion.
