Exploring the coordinative behaviour and molecular architecture of new PhHg(II)/Hg(II) dithiocarbamate complexes

摘要: Abstract New dithiocarbamate (dtc) complexes of the form [(PhHg)2L] (L = bis(furfurylaminomethyl)benzene dtc L1 (1)), [PhHg(L)] (L = ethyl-1-piperazinecarboxylate L2 (2), thiomorpholine L3 (3), N-(N-methyl-2-pyrrole)-N-(methyl-3-pyridyl) L4 (4), N-(N′-methyl-2-pyrrole)-N-(methyl-benzyl) L5 (5)) and [Hg(L)2] (L = bis(N-methyl-3-pyridyl) L6 (6), (7), (8)) have been synthesized fully characterised; their structures revealed by X-ray crystallography. 1–5 show similar with metal atoms forming two strong bonds, to carbon one sulfur atom from bidentate ligand in an approximate linear arrangement additional weak bond second atom. However very different packing arrangements. 1 is a less common type dinuclear organomercury complex containing units linked 1,4-dibenzyl group. In 6, lies at centre distorted square plane coordinated ligands, axially bonded on adjacent molecules 2-D polymeric chain. 7 8 Hg tetrahedrally four ligands. Complexes 2, 5, luminescence solution.
