Synthesis and Crystal Structure of Bis[O,O′-di(2-phenylethyl)dithiophosphato](α,α′-bipyridine)copper(II)

A ternary adduct Cu[S2P(OCH2CH2Ph)(2)](2) bipy (bipy=alpha,alpha-bipyridine) was synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction The crystal belongs to the triclinic system, space group P (1) over bar with a=10 2320(2), b=11 5249(3), c=18 0916(3) angstrom, alpha=98 95(1), beta=103 601(1), gamma=91 272(2)degrees, V=2044 49(7) angstrom(3), Z=2, D-c=1 453 g/cm(3), T=153(2) K, C42H44CuN2O4P2S4, M-r=894 51, lambda(MoK alpha)=0 71073 angstrom, mu=0 86 mm(-1), S=0999, (Delta/sigma)(max)=0 002, the final R=0 0243 and wR=0 0704 A total of 9221 unique reflections were collected, of which 8573 with I>2 sigma(I) were observed The Cu(II) atom is five-coordinated in a rather distorted trigonal bipyramidal geometry (tau value=0 537) The Cu-S distances range from 2 3491(4) to 2 4829(4) angstrom, and the Cu-N distances are 1 9987(12) and 2 0584(11) angstrom, respectively An interesting feature of this adduct resides m its two-dimensional (2D) open framework constructing through hydrogen bonding and pi-pi interactions
