Abstract

The syntheses, spectroscopic characterization (IR, 1H and 31P NMR, ESI-MS) and conductivity studies of the mixed N,Pdonor complexes of copper(I) thiocyanate: [Cu(NCS)(py)2- (PPh3)], (2), [Cu(NCS)(Mepy)(PPh3)]2, (3), [Cu(NCS)(phen)- (PPh3)], (4), [Cu(NCS)(bpy)(PPh3)], (5), [Cu(NCS)(bpy)- (PPh2py)], (6), [Cu(NCS)(py)(PPh2py)], (7), (py = pyridine; Mepy = 2-methylpyridine; phen = 1,10-phenanthroline, bpy = 2,2?-bipyridyl), together with single-crystal X-ray structural characterizations of 2, 3, 4 (new polymorph), 5 and 6 are reported, which provides an opportunity to study the effect of the introduction of a pair of nitrogen donors, both unidentate and chelate, on the bonding parameters of the Cu/NCS/P system.
