摘要：A new 1D coordination polymer [Me4N](3){[Mn(L)][Nb6Cl12(CN)(6)]}center dot 3MeCN center dot H2O (1) (L = acacen (2-) = N,N'-bis(acetylacetone)-1,2-ethylenediimine) was synthesized from reaction between [Me4N](4)[Nb6Cl12(CN)(6)] and [Mn(L)]Cl in acetonitrile. The crystal structure of 1 was determined from single-crystal X-ray diffraction analysis. Compound 1 crystallizes in the tetragonal system, space group I4(1)/a (No. 88), a = 30.585(4), c = 27.348(6) , V = 25582(7) (3), Z = 16. Its 1D framework consists of chains formed of metal clusters and Mn(L) complexes linked to each other by Nb-Ca parts per thousand N-Mn-Na parts per thousand C-Nb linkages. The chains extend along the a and b crystallographic axes and are related to each other by 4(1) screw axis. The chains are held together by [Me4N](+) cations and solvent molecules located in channels running between the chains. 1 and the previously reported 1D coordination polymer [Me4N](3){[Mn(5-MeO-salen)][Nb6Cl12(CN)(6)]} (3) differ from each other in terms of their synthesis and their structural characteristics.
