Crystal and molecular structure of O-methylbenzoin methylmercurio-(p-tolylsulphonyl)hydrazone

Abstract

The structure of the title compound was obtained by the heavy-atom method and refined to R 0.08 for 2 386 observed reflections. Crystals are monoclinic, space group P2₁/a, with unit-cell demensions a= 10.695(1), b= 14.166(2), c= 15.032(3)Å, β= 104.06(3)°, and Z= 4. The co-ordination around mercury is linear, with a nitrogen atom from the azo-group on the side opposite to a methyl group, with Hg–N 2.05(2), Hg–C 2.04(2)Å, and N–Hg–C 175(5)°. Some chemical features of the hydrazones are discussed in terms of molecular geometry.
