Bis[(1,10-phenanthroline-κ²N,N′)bis­(triphenyl­phosphane-κP)copper(I)] nona­deca­oxidohexa­molybdate(VI)

The title compound, [Cu(C₁₂H₈N₂)(C₁₈H₁₅P)₂]₂[Mo₆O₁₉], was obtained by co-crystallization of the mixed-ligand copper complex cation (1,10-phenanthroline)bis­(triphenyl­phos­phane)copper(I), [Cu(phen)(PPh₃)₂]⁺, with the Lindquist polyanion [Mo₆O₁₉]²⁻. The asymmetric unit consists of half a Lindquist anion and one [Cu(phen)(PPh₃)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.
