Cluster cyanide-bridged heterometallic coordination polymers:: synthesis and crystal structures of compounds [{Cu2(dien)2(CN)}2{Mo4Te4(CN)12}] •14.5H2O and (H3O)3K[{Mn(H2O)2}2{Mn(H2O)2(NO3)}4{W4Te4(CN)12}2] • 8H2O

The reactions of anionic molybdenum and tungsten cyanide cuboidal clusters with Cull and Mn-11 salts afforded two new cyanide-bridged heterometallic coordination polymers with the composition [(Cu-2(dien)(2)(CN)}(2){Mo4Te4(CN)(12)}]center dot 14.5H(2)O (1) and (H3O)(3)K[(Mn(H2O)(2){Mn(H2O)(2)(NO3)}4{W4Te4(CN)(12)}(2)] center dot 8H(2)O (2). The structures of these compounds were established by X-ray diffraction analysis. Compound 1 has a layered structure, in which the cuboidal cluster fragments (Mo4Te4(CN)(12))(6-) are linked to the copper atoms of the dinuclear fragments {(H2O)(dien)Cu(mu-CN)Cu(dielt)(H2O)} through the bridging CN groups. Coordination polymer 2 has a framework structure, in which the cluster fragments (W4Te4(CN)(12)}(6-) are linked to the manganese(n) aqua complexes of two types, viz., the dinuclear fragment {Mn(mu(2)-H2O)(2)Mn) and the tetranuclear cyclic fragment {(H2O)(2)Mn(mu(2)-NO3)}(4), through the bridging CN groups.
