Solid state packing of [Rh(β-diketonato)(CO)2] complexes. Crystal structure of [Rh(PhCOCHCOC4H3S)(CO)2]

A neutral columnar stacking of [Rh(PhCOCHCOC4H3S)(CO)2] molecules was obtained in the crystalline solid state, i.e. the complex forms “molecular wires” in the solid state. The metal–metal interactions of [Rh(PhCOCHCOC4H3S)(CO)2] and related [Rh(β-diketonato)(CO)2] complexes show, that [Rh(β-diketonato)(CO)2] complexes generally form a dimer-like arrangement, with a RhIRhI distance of 3.18–3.54 Å. The dimeric units either stack in infinite chains, or interact with each other via weak Rhπ, or weak hydrogen bond interactions.
