| 中文摘要 | reaction of thiamine or thiamine monophosphate (tmp) with k2pt(no2)(4) afforded a metal complex, pt(thiamine)(no2)(3) (1), and two salt-type compounds, (h-thiamine)[pt(no2)(4)]. 2h(2)o (2) and (tmp)(2)[pt(no2)(4)]. 2h(2)o (3), which were structurally characterized by x-ray diffraction. in 1, the square-planar pt2+ ion is coordinated to the pyrimidine n(1'), a usual metal-binding site, and three no2- groups. the thiamine molecule exists as a monovalent cation in 1 and a divalent cation in 2 while the tmp molecule is a monovalent cation in 3. in each compound, thiamine or tmp adopts the usual f conformation and forms two types of host-guest-like interactions with anions, which are of the bridging forms, c(2)-h . . . anion . . . pyrimidine-ring and n(4'1)-h(...)anion(...)thiazolium-ring. in 3, there is an additional anion-bridging interaction between the pyrimidine and thiazolium rings of tmp, being of the form c(6')-h . . . anion . . . thiazolium-ring. the salts 2 and 3 show similar hydrogen-bonded cyclic dimers of thiamine or tmp between which the anions are held. results are compared with those of the other thiamine-platinum complexes.
