Preparation and Crystal Structural Study of a Novel Coordinated Polymer [HgI2(4-bped)2] (bped = bis(4-pyridyl)ethylene diamine)

A novel coordinated polymer [HgI2(4-bped)2] was synthesized through the reaction of bis(4-pyridyl)ethylene diamine and HgI2 in mixed MeOH–THF (5:2). The crystal structural analysis indicated that the complex crystallized in a monoclinic space group P21/c, a = 10.8392(12), b = 19.841(2), c = 8.8279(10), β = 95.452(2), V = 1889.9(4) A3, Z = 4. The complex possessed a novel three-dimensional supramolecular framework formed by hydrogen bonds among repeating [HgI2(4-bped)]2 dimeric units.
