| Abstract: | The crystal of the title compound, Co(en)3]4Ru(CN)6]3(10H2O (en = ethylenediamine, C2H8N2), is formed from the octahedral cations of Co(en)33+ and anions of Ru(CN)64-. The Co atom is coordinated to six nitrogen atoms of ethylenediamines in a ( configuration and the Ru atom is also coordinated to six carbon atoms of cyanides. There is no bridging-cyanide between the metal ions in the structure. The crystal is of monoclinic, space group P21/c with a = 17.686(4), b = 14.496(4), c = 18.019(7) (A。）, β = 116.07(2), V = 4150(2) (A。）3, Z = 2, Mr = 1908.60, C42H116N42O10Co4Ru3, ((MoK() = 1.391 mm-1, Dc = 1.527 g/cm3, F(000) = 2084, R = 0.0520 and wR = 0.1070 for 5443 observed reflections (I > 2((I)). |
