[4'-(3-Pyridyl)-2,2';6',2''-terpyridine]dithiocyanatocopper(II)

Abstract top

In the title compound, [Cu(NCS)2(C20H14N4)], the Cu atom is five-coordinated in a tetragonal-pyramidal geometry.

Comment top

The heterocyclic ligand 4'-(3-pyridyl)-2,2':6'2''-terpyridine was synthesized according to literature methods (Constable et al., 1992). As a excellent tridentate chelating ligand, it can furnish complexes from a large range of metal salts. The structure of the title compound, (I), obtained from copper(I) thiocyanate is shown in Fig. 1. The Cu(II) atom is chelated by a tridentate terpydine in a cis-cis configuration and two independent thiocyanate in a five-coordinate environment and shows distorted tetragonal pyramid geometry (Fig. 1). The Cu—N bonds range from 1.931 (3)Å to 2.143 (4)Å are comparable with those reported (Hou et al., 2004). In the monomer, one thiocyanate was in the apical site while the terpyridine and the other one thiocyanate were at the equatorial positions.

Experimental top

The mixture of CuSCN (0.0125 g, 0.1 mmol), 4'-(3-pyridyl)-2,2':6'2''-terpyridine (0.0155 g, 0.05 mmol), acetonnitril (6 ml) were placed and sealed in a 10 ml Teflon-lined stainless steel reactor and heated to 140°C for 72 h, then cooled down to room temperature at a rate of 2°C per 20 min. Green block single crystals suitable for X-ray diffraction were obtained in ca. 60% yield

Refinement top

Hydrogen atoms were placed in calculated positions (C–H 0.93 Å; U(H) = 1.2UeqC) and were included in the refinement in the riding model approximation.
