fac-Tri­carbonyl(4,4′-di­methyl-2,2′-bi­pyridine)­tri­phenyl­tin(II)­rhenium(I)

The title organometallic compound, fac-tri­carbonyl-2κ³C-(4,4′-di­methyl-2,2′-bi­pyridine)-2κ²N,N′-tri­phenyl-1κ³C¹-tin(II)­rhenium(I)(Sn—Re), [ReSn(C₆H₅)₃(C₁₂H₁₂N₂)(CO)₃], con­tains three unique π–π stacking interactions. The result is an infinite chain of uninterrupted alternating intra- and intermolecular offset π–π stacking interactions throughout the crystal lattice. This extended π–π stacking arrangement, and an additional isolated intramolecular π–π interaction between the remaining 4,4′-di­methyl-2,2′-bi­pyridine ring and a second phenyl group, impose geometric constraints on the Re and Sn atoms, yielding distorted octahedral and tetrahedral coordinations, respectively, for the metal centers.
