| 中文摘要 | the crystal structure of thiamine iodide sesquihydrate has been determined by x-ray diffraction methods as a host-guest model for coenzyme-substrate interactions. the asymmetric unit contains two chemical units. both the thiamine molecules a and b, which are crystallographically independent, assume the usual f conformation and have a disordered hydroxyethyl side chain. an iodide anion (or a water molecule) bridges the pyrimidine and thiazolium rings of molecule a (or b) by forming a hydrogen bond with the amino group and an electrostatic contact with the thiazolium ring to stabilize the molecular conformation. in the crystal the thiamine molecules self-associate to form a pipe-like polymeric structure, in which four thiamine hosts surround an iodide guest and hold it through c(2)-h...i hydrogen bonds and thiazolium...i electrostatic interactions. crystal data: c12h17n4os+.i- . 1.5 h2o, monoclinic, p2(1)/c, a = 12.585(2), b = 25.303(5), c = 12.030(2) angstrom, beta = 115.15(1)degrees, v = 3468(1) angtrom3, z = 8, d(c) = 1.606 g cm-3, r = 0.045 for 3328 observed reflections. |
