摘要

During alternating-current electrochemical synthesis of copper(I) pi-complex of [CUCl{C6H4N3(C3H5)}] composition, starting from ethanol solution, containing CUCl(2)center dot 2H(2)O and 1-allylbenzotriazole, green crystals of intermediate [(Cu3Cl6)-Cl-11{C6H4N3(C3H5)}(4]) (1) compound has been obtained upon 24 h. After some days these crystals transform into red ones of [(CU2CI4)-C-11{C6H4N3(C3H5)}3] (II). Both compounds were X-Ray structurally investigated. Crystals of I are triclinic, sp.gr. P 1, a= 9.1329(9), b=10.0352(4), c=12.239(3) angstrom, alpha=76.443(13), beta=84.470(14), gamma=76.808(7)degrees, V=1060.5(3) angstrom(3), R=0.0414 for 3311 reflections. 11: monoclinic, C2/c, a=13.828(1), b=15.044(2), c= 10.702(1) angstrom, beta=91.36(1)degrees, V=2225.7(4) angstrom(3), R=0.050 for 1495 reflections. In both compounds each benzotriazole core coordinates two copper atoms using two nitrogen atoms in 2 and 3 positions. Isolated Cu3Cl6 fragments in I are condensed along [001] direction into infinite chains [CUCl2]n in II. Finally, red crystals of II transform into colorless ones of the earlier studied copper(l) pi-complex of CUCl center dot C6H4N3(C3H5) composition.
