Bis[(1,10-phenanthroline-κ(2) N,N′)bis­(triphenyl­phosphane-κP)copper(I)] nona­deca­oxidohexa­molybdate(VI)

The title compound, [Cu(C(12)H(8)N(2))(C(18)H(15)P)(2)](2)[Mo(6)O(19)], was obtained by co-crystallization of the mixed-ligand copper complex cation (1,10-phenanthroline)bis­(triphenyl­phos­phane)copper(I), [Cu(phen)(PPh(3))(2)](+), with the Lindquist polyanion [Mo(6)O(19)](2−). The asymmetric unit consists of half a Lindquist anion and one [Cu(phen)(PPh(3))(2)](+) cationic complex. In the cation, there are intra­molecular π–π inter­actions [centroid–centroid distances = 3.617 (2) and 3.7272 (18) Å]. This inorganic–organic adduct is connected by C—H⋯O hydrogen bonds, forming a two dimensional network lying in the ab plane. These networks are connected by C—H⋯π inter­actions into a three-dimensional structure.
