| Popis: | The crystal structure of (triphenylphosphine)(nitrosyl)(O-cyclopentyldithiocarbonate)nickel, Ni(NO)(PPh3)(S2COC5H9), has been determined from three-dimensional X-ray diffraction data, collected on a computer-controlled Philips PW1100 single-crystal diffractometer (2894 observed reflections). The crystals are monoclinic, space group P21/c, with a = 10.416(1), b = 9.890(1), c = 23.876(4) Å, β = 97.84(1)° and Z = 4. The structure was solved by direct phase determination with MULTAN and refined by least-squares calculations to a final R = 0.038 (Rw = 0.040). The Ni atom is fourfold coordinated by two S, one P and one N atom, which form a strongly distorted tetrahedron. The xanthate ligand acts as bidentate, while the group NiNO is slightly bent. The Ni – S distances are practically equal, 2.328(1) – 2.329(1) Å, and the Ni – P and Ni – N distances are 2.240(1) and 1.650(4) Å respectively. In the nitrosyl ligand the N – O distance is 1.136(5) Å, while in the xanthate and the triphenylphosphine ligands the determined distances and angles are as expected. The crystal cohesion may be attributed to normal van der Waals forces. |
