Comparison of calculated vibrational frequencies and bond lengths with experimental data is made whenever possible. , E-mail: compounds such as NbF, which consists of a seven-fold coordinated Nb bonded to two distorted octahedra via edge sharing. The overall arrangement is that of a coordination polymer assisted by aurophilic and hydrogen-bonded interactions.Īn ionic force-field study of monomers, dimers and higher polymers in pentafluoride vaporsĮnergy Technology Data Exchange (ETDEWEB)Ĭicek Onem, Z.
