چکیده
In the title compound, [NiCl(2)(C(14)H(32)P(2))]·2C(12)H(9)N, the neutral [Ni(dppe)Cl(2)] complex [dppe is 1,2-bis-(diisopropyl-phosphan-yl)ethane] consists of a tetracoordinated Ni(2+) cation and has a crystallographic twofold axis passing through the metal atom and the mid-point of the CH(2)-CH(2) bond of the dppe ligand. The metal atom shows slight tetra-hedral distortion from an ideal square-planar coordination geometry, as reflected in the dihedral angle between NiCl(2) and NiP(2) planes of 15.32 (2)°. The 9H-carbazole ring system is essentially planar (r.m.s. deviation = 0.022 Å). In the crystal packing, there are two symmetry-related 9H-carbazole mol-ecules between two adjacent Ni(II) complexes, with an angle between the carbazole mean planes of ca 77°.
