One-dimensional metal string complexes

The metal string complexes with different metal ions and various lengths ha ve been successfully synthesized and structurally characterized. The crysta l and molecular structure of nonanickel complex [Ni-9(mu(9)-(peptea)(4)Cl-2 ] which is the longest metal string at this moment will be reported. Crysta l data for [Ni-9(mu(9)-(peptra)(4)Cl-2] (C2H4Cl2)(10): Space group, monocli nic C 2/c, a = 27.0453(6), b = 42.6678(5), c = 37.4268(6) Angstrom, beta = 109.539(1)degrees, V = 40702(1) Angstrom(3), Z = 12, R-F = 12% for the obse rved reflections (I > 2 sigma(1)). The band structure calculation of infini te one-dimensional metal chains of Ni-II and Cr-II based on the structure o f nonanickel complex will be presented. Finally, the metal string complexes [(MnL4X2)-L-II] will be chemisorbed on the Ag or Au surface and the potent ial application of these complexes as a molecular metal wire will be demons trated.
