(2-Methyl-4-oxo-4H-pyran-3-olato-κO,O)bis-(triphenyl-phosphane-κP)copper(I)-triphenyl-phosphane-methanol (1/1/1).

In the title compound, [Cu(C(6)H(5)O(3))(C(18)H(15)P)(2)]·C(18)H(15)P·CH(3)OH, the pyran-4-one ring is appromimately planar (r.m.s deviation = 0.0138 Å), with the Cu(I) atom 0.451 (5) Šout of the plane. The Cu(I) atom has a distorted tetra-hedral coordination. The O-Cu-O angle is 80.07 (8)° and the P-Cu-P angle is 123.49 (3)°. The crystal packing is stablized by intra-molecular C-H⋯O inter-actions and inter-molecular C-H⋯O and O-H⋯O inter-actions.
