Synthesis and structure of a novel one-dimensional chain compound formed by copper(II) and nitronyl nitroxide radical

摘要

A novel compound formed by copper(II) and a carboxy-substituted nitronyl nitroxide of formula [Cu-2(NITpBAH)(2)Cl-4] (NITpBAH = [2-(4'-carboxy-phenyl)-4,4,5,5-tetramethyl-4,5- dihydro-1H-imidazol-1-oxyl-3-oxide]) has been synthesized. The compound crystallizes in the monoclinic space group P2(1)/c with a = 9.5464(10), b = 12.4501(12), c = 14.3627(14) Angstrom, beta = 95.200(2) degrees, and Z = 2. X-ray analysis reveals [Cu-2(NITpBAH)(2)Cl-4] units to be linked into infinite chains by radical bridging ligands with N-O of nitronyl nitroxide and substituted carboxy; there are the weak hydrogen bond interactions between chains.
