Formation of a Spiral-Shaped Inorganic-Organic Hybrid Chain, [CuII(2,2-bipy)(H2O)2Al(OH)6Mo6O18]nn-: Influence of Intra- and Interchain Supramolecular Interactions

A novel chainlike coordination polymer [CuII(2,2ʹ-bipy)(H2O)2Al(OH)6Mo6O18]nn-, formed from a heteropolyanion [Al(OH)6Mo6O18]3- as a building unit and a copper(II) complex fragment, [CuII(2,2ʹ-bipy)(H2O)2]2+, as a linker, provides the first example of an extended structure based on an Anderson type of polyanion and a transition metal complex with organic ligand. The intra- and interchain O-H···O hydrogen-bonding interactions are seemingly responsible for the spiral shape of this chain.
