Abstract

The generation of polarity in the solid state necessitates ordered, polar basic-building units (BBUs). This paper examines the evolution of ordered BBUs of 1D chains constructed of early transition metals (ETMs) and late transition metals. The cause of polar distortion orientation is illustrated with subtle alterations in the heterotypic structures of one previously reported compound (CuNbOF 5(H 2O) 2(pyz) 3) and three new hybrid materials, presented here: CuNbOF 5(H 2O) 4(pyz) 2 (1), CuVOF 5(H 2O) 4(pyz) 2 (2) and CuVOF 5(H 2O) 2(pyz) 3 (3) (pyz=pyrazine). In contrast to the [NbOF 5] 2- octahedra of CuNbOF 5(H 2O) 2(pyz) 3 and compound (1) that have oxide ligands within the 1D BBUs, the [VOF 5] 2- octahedra of compounds (2) and (3) contain disordered oxide ligands perpendicular to the chains. To create polar 1D BBUs in the solid state, one must have an understanding of how to direct distortions. We demonstrate that the choice of specific polar BBUs within a distinct environment is necessary for orientational order of the ETM anions.
