Crystal and molecular structure of (2,2′-bipyridyl)methylmercury(II) nitrate, a complex with irregular three-co-ordination

Abstract

Crystals of the title compound are triclinic, with a= 10.299(5), b= 9.289(5), c= 6.841 (4)Å, α= 88.98(4), β= 105.57(5), γ= 84.81 (4)°, Z= 2, and space group P. The structure was solved by conventional Patterson and Fourier methods and refined by least-squares techniques to R 0.061 for 1 325 reflections collected by diffractometer. The complex has a planar C,Hg,N,N′ group with unsymmetrically chelated 2,2′-bipyridyl and three-co-ordinate mercury: Hg–C 2.07(5), Hg–N 2.24(3), and Hg–N′2.43(3)Å; C–Hg–N 164(1),C–Hg–N′126(1), and N-Hg-N′(chelate angle) 69(1)°. The nitrate ion is regular and unto-ordinated.
