In the title compound, [NiCl2(C14H32P2)]·2C12H9N, the neutral [Ni(dppe)Cl2] complex [dppe is 1,2-bis(diisopropylphosphanyl)ethane] consists of a tetracoordinated Ni2+ cation and has a crystallographic twofold axis passing through the metal atom and the mid-point of the CH2-CH2 bond of the dppe ligand. The metal atom shows slight tetrahedral distortion from an ideal square-planar coordination geometry, as reflected in the dihedral angle between NiCl2 and NiP2 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 molecules between two adjacent NiII complexes, with an angle between the carbazole mean planes of ca 77°.
