Synthesis,Characterization and Crystal Structure of New Organotin Copper Cyanide Three-Dimensional Supramolecular Coordination Polymer Containing Quinoxaline Molecule

Self assembly of K₃[Cu(CN)₄] with Me₃SnCl and quinoxaline (qox) affords the new organotin ternary adduct _∞³[Cu₂(CN)₃·Me₃Sn·qox], 1, as orange platelet crystals. The supramolecular architecture of 1 consists of [Cu₂(CN)₃]⁻ building blocks connected by the (Me₃Sn)⁺ cations forming infinite corrugated 1D-chains. The chains are bridged by the qox molecules forming 2D-layers containing fused distorted polygons. The layers are interwoven forming 3D-network structure, which are stabilized by close packing effects such as H-bonds as well as Cu···Cu and π–π interactions. IR and mass spectra as well as TGA are investigated.
