Abstract

<p>Complexes [Hg(bipyP<sub>2</sub>)Br<sub>2</sub>] (<strong>2</strong>), [Hg(bipyP<sub>2</sub>)BrCl] (<strong>3</strong>), and [Hg(bipyP<sub>2</sub>)Cl<sub>2</sub>] (<strong>4</strong>), where bipyP<sub>2</sub> is tetraethyl 2,2'-bipyridyl-4,4'-diphosphonate (<strong>1</strong>), were prepared and their crystal structures were determined. Coordination of the phosphonate group was only found in <strong>4</strong>. In this compound, the coordination sphere of Hg(II) contains two Cl atoms, two N atoms from the bipyridine chelate and O atom from phosphonate group and thus, the coordination number is five. The presence of Br atoms in the coordination sphere of complexes <strong>2</strong> and <strong>3</strong> results in the formation of tetrahedral environment (coordination number four) without any interaction with phosphonate. The coordination of the phosphonate group in <strong>4</strong> was also confirmed by IR spectroscopy. <br />
