Abstract

A systematic theoretic study on clusters containing edge-bridged octahedral metal units [Nb 6Cl 12] n (n = 2, 3, or 4) and a large variety of ligands has been performed. The benchmark results on the [Nb 6Cl 12 i] n+ and [Nb 6Cl 12 iCl 6 a] n (n = 2, 3 or 4) cluster units demonstrated the reliability of GGA PBE functional in combination with ZORA TZP basis set for the Nb-containing coordination compounds. The geometrical, electronic, and vibrational properties of large variety of substituted Nb 6Cl 12 iY 6 a clusters have been provided. One-and two-dimensional structures with a [Nb 6Cl 12 i (Bipyr) xCl 6-x a] (x = 2 and 4) building blocks have been proposed as good and stable candidates for new coordination polydimensional materials.
