摘要

A systematic theoretic study on clusters containing edge-bridged octahedral metal units [Nb6Cl12] n (n = 2, 3, or 4) and a large variety of ligands has been performed. The benchmark results on the [Nb6Cl 12 i ] n+ and [Nb6Cl 12 i Cl 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 Nb6Cl 12 i Y 6 a clusters have been provided. One- and two-dimensional structures with a [Nb6Cl 12 i (Bipyr) x Cl 6−x a ] (x = 2 and 4) building blocks have been proposed as good and stable candidates for new coordination polydimensional materials.
