Synthesis, Crystal Structure, and Luminescence of a Three-Dimensional Supramolecular Compound Based on a Dinuclear Tin Cluster

Abstract

A three-dimensional (3D) supramolecular compound, [(phen)LSnS]₂·(H₂O)₂ (phen = 1,10-phenanthroline, L = mercaptoacetic acid), has been synthesized and the crystal structure was determined by a single crystal X-ray diffraction study. 1 is triclinic, space group P-1 with a = 6.695(1) Å, b = 10.929(2) Å, c = 12.117(2) Å, α = 114.55(3)°, β = 93.53(2)°, γ = 104.06(3)°, and Z = 1. The dinuclear cluster of [(phen)LSnS]₂ and H₂O are linked into a 3D supramolecular framework by a combination of O[sbnd]H…O, C[sbnd]H…O hydrogen bonds and π–π stacking interactions. Its luminescence property is discussed.
