Chloro­bis­(tri­phenyl­phosphine)­nickel(I) tetra­hydro­furan solvate and an unsolvated trigonal phase of chloro­tris­(tri­phenyl­phosphine)­nickel(I)

In [NiCl(C₁₈H₁₅P)₂]·C₄H₈O, the Ni atom is coordinated by three ligands in a distorted trigonal–planar configuration, with a P—Ni—P angle of 111.52 (2)°. In [NiCl(C₁₈H₁₅P)₃], there are three independent mol­ecules in the asymmetric unit, with each Ni—Cl bond on a crystallographic threefold rotation axis. Each Ni centre is tetrahedrally bound. The Ni atoms in both compounds have a d⁹ configuration and a formal oxidation state of Ni^I. A comparison is made between the form of [NiCl(PPh₃)₃] presented here and that of a known toluene solvate.
