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 i n a distorted trigonal-planar configuration, with a P-Ni-P angle of 111.52 (2)degrees. 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 d(9) 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.
