Formation of a 1D-polymeric chain of Hg building blocks through C-C coupling under ambient conditions.

A novel C-C coupled 1D-polymeric chain (1) is obtained by reaction of HgCl2 and hmp-H (2-(2-hydroxymethyl pyridine)) (1 : 1) in MeOH at ambient temperature. However, a new class of μ-oxo and μ-chloro bridged polymers (2) has been obtained by altering the metal : ligand ratio to 1 : 2.

Bis[2-(2-hy-droxy-meth-yl)pyridine-κ(2)N,O](pivalato-κO)copper(II).

The structure of the centrosymmetric title complex, [Cu(C(5)H(9)O(2))(2)(C(6)H(7)NO)(2)], has the Cu(II) atom on a centre of inversion. The Cu(II) atom is six-coordinate with a distorted octa-hedral geometry, defined by the N and O atoms of the chelating 2-(2-hydroxymethyl)pyridine ligands and two carboxyl-ate O atoms from two monodentate pivalate ions. The crystal packing is stabilized by inter-molecular C-H⋯O and intra-molecular O-H⋯O hydrogen-bond inter-actions.
