| 中文摘要 | the crystal structure of [mn(thiamine)cl2(h2o)]2[thiamine]2cl4.2h2o has been determined by x-ray diffraction methods. the compound contains a cyclic dimer of a complex cation with two thiamine ligands bridged by two mn(ii) ions across a crystallographic center of symmetry. each mn(ii) is coordinated by two chloride atoms, a water molecule, a n(1') atom of the pyrimidine from a thiamine and an o(53) atom of the hydroxyethyl side chain from another thiamine. there are two free-base thiamine molecules related by a center of symmetry in the unit cell, which form a base-pair through the hydrogen bonds. both the independent thiamine molecules in the asymmetric unit assume the common f conformation with phi-t = 10.0(9) and 3.6(10) and phi-p = 85.6(7) and 79.6(7), respectively. the compound provides a possible model for a metal-bridged enzyme-coenzyme complex in thiamine catalysis. crystallographic data: triclinic, space group p1bar, a = 12.441(4), b = 13.572(4), c = 11.267(3) angstrom, alpha = 103.15(2), beta 89.03(3), gamma = 115.64(2)-degrees, z = 1, d(calc) = 1.524 g cm-3, and r = 0.050 for 3019 observed reflections with i > 3-sigma(i). |
