摘要：
Two novel polymeric bismuth(III) complexes with dmit, {[Et4N][Bi(dmit)(2)]}(n) (1) and {[Et4N](2)[Bi-2(dmit)(4)]. Et2O}(n) (2), have been synthesized and structurally characterized. Complex 1 is a one-dimensional polymer consisting of repeating Bi(dmit), units in which each Bi atom is six-coordinated by six sulfur atoms from dmit ligands to form a distorted octahedron. Whereas the anions of complex 2 can be described as polymeric chains being composed of the repeating dimeric Bi-2(dmit)(4) units, in which the environment of the Bi atoms are similar to that in complex 1. In contrast to 1, there exists S ... S contacts less than 3.7 Angstrom between two neighboring independent polymeric anions in complex 2, through which complex 2 forms a quasi two-dimensional structure. (C) 1999 Elsevier Science Ltd.
