Abstract
A new compound with the formula PbUO2(mac)4, where mac is the methacrylate ion CH2C(CH3)COO−, has been synthesized and studied by X-ray diffraction and IR spectroscopy. The equatorial plane of a UO7 pentagonal bipyramid contains the oxygen atoms of four anions, three of which are coordinated to the uranyl ions monodentately, and one is coordinated bidentately, forming mononuclear complexes [UO2(mac)4]2−. Each lead ion is bound to eight oxygen atoms of five methacrylate ions of three such complexes. As a result, lead ions bond uranium-containing complexes into electroneutral chains [PbUO2(mac)4], which are the main structural units of crystals. The different roles of the four crystallographically nonequivalent methacrylate ions in the crystal structure determine the crystal-chemical formulas of the chains as A′AB01B11(B21)2, where A′ = Pb2+; A=UO 2+2 ; B01, B11, and B21 = mac. The chains are linked by the system of hydrogen bonds to form a framework. The effect of the nature of R2+ cations on the structure of methacrylate uranylates is considered.
