Structure of Bis(2,2'-bipyridyl)thioeyanatoeopper(II) Nitrate Monohydrate

Abstract

[Cu(NCS)(C IoHsN2)2]NO3.H2 O, M r = 514.02, triclinic, Pi, a=-12.098 (4), b= 12.810(5), c= 7.777 (2)/~, a= 102.80 (3), fl= 107.56 (2), y-- 76.03 (3) ° , V= 1100.6(6) A 3, Z=2, D m=1.556, Dx= 1.551 Mgm -3, ~.(Mo Ka) = 0.7107 .&, /t= 0.2183 mm -~, F(000) = 526, T= 293 K, R = 0.041 for 4104 unique observed reflections. The Cu atom is pentacoordinated to the four N atoms of the bipyridyl ligands and the N atom of the thiocyanato group in a 0108-2701/88/071191-03503.00 near-regular trigonal bipyramidal arrangement, where only three distances differ significantly: 1.992(2) (average) for the axial bonds, 2.079 (3) (average) and 2.010 (3) A for the equatorial bonds.
