Polymeric disodium (mu-trans-4,4 ‘-ethylenedipyridyl)bis mu-5-sulfoisophthalato(3-) -dicadmate(II) hexahydrate

摘要

The title crystal structure, {Na-2[Cd-2(C12H10N2)(C8H3O7S)(2)].-6H(2)O}(n), contains pentagonal-bipyramidal Cd atoms and octahedral Na atoms. The Cd atom is chelated by two carboxyl groups of adjacent 5-sulfoisophthalate(3-) trianions, and it is also coordinated by the pyridyl group of the centrosymmetric heterocycle, the coordinating atoms comprising the pentagonal plane around the metal atom. In the network structure, the Na atoms occupy the voids in the network such that they exist in a six-coordinate geometry.
