Crystal structure of kinetic and thermodynamic coordination networks formed between 3,3'-dipyridylethyne and copper bromide.
Reaction of copper(I) bromide with 3,3'-dipyridylethyne yielded rhomboid yellow crystals that are stable when removed from the mother liquor. X-Ray crystallographic analysis identified the one-dimensional coordination polymer formed with pairs of dipyridyl ligands bridging rhombic CuBr2Cu units. The crystals left in the mother liquor re-dissolved and formed orange hexagonal prisms that were shown to be a stable three-dimensional network comprising interwoven ligand-copper ribbons linked together by infinite copper-bromide chains.
