Synthesis and crystal structure of mercury complex of saccharin with pyridine [Hg(sac)(2)(py)(2)]

The structure of the mercury saccharinate complex with pyridine has been studied by IR and single crystal X-ray diffraction methods. The compound was,crystallized in the monoclinic space group P2(1)/n with unit cell dimensions of a = 9.8114(2) b = 21.2444(3), c = 12.0557(5), 8 = 97.8431(8)degrees, Z = 4, and the crystal structure was solved to an R value of 0.0425 for 5700 observations. The Hg atom has slightly distorted tetrahedral configuration with four nitrogen (N) atoms from two pyridine and two saccharinate anions in the complex.
