catena-Poly[[dichloridomercury(II)]-N′-nicotinoylnicotinohydrazide]

The title complex, [HgCl(2)(C(12)H(10)N(4)O(2))](n), is composed of one Hg(II) ion, one nnh ligand (nnh = N'-nicotinoylnicotinohydrazide) and two coordinated chloride ions. The Hg(II) ion shows a distorted tetra-hedral geometry, being surrounded by two N atoms from two nnh ligands and two chloride ions. Due to the bridging role of nnh, the Hg(II) atoms are… (More)
