N2  - The crystal structure of the title compound, [Cu{CS(NH2)2}2(phen)] I,phen, has been determined by X-ray diffraction with direct methods, and refined by least squares to a residual of 0.043 for 5383 ?observed? reflections. Crystals are triclinic, P&#299;, a 13.263(8), b 12.449(2), c 10.214(2) &#506;, &#945; 113.20(2), &#946; 90.16(2), &#947; 112.72(2)°, Z 2. The coordination about the copper is pseudo-tetrahedral, distorted by the bite of the phenanthroline ligand [Cu-S, 2.295(2), 2.280(1) &#506;; Cu-N, 2.072(4), 2.089(5) &#506;, N-Cu-N, 81.0(2)°; S-Cu-S, 117.31(6)°; N-Cu-S, 107.7(11)-117.23(9)°]. In addition the structure provides the first example of the determination of the geometry of the uncoordinated o- phenanthro-line molecule. The stereochemistry of the [M(bidentate)(unidentate)2] coordination type is considered in terms of a repulsion model.
