Syntheses and structures of two new uranyl complexes [UO_2(DPDPU)_2(NO_3)_2](C_6H_5CH_3) and [UO_2(PMBP)_2(DPDPU)](CH_3C_6H_4CH_3)_(0.5)

摘要

Two new uranyl complexes [UO_2(DPDPU)_2(NO_3)_2](C_6H_5CH_3) (1) and [UO_2(PMBP)_2 (DPDPU)](CH_3C_6H4CH_3)_(0.5) (2), (DPDPU = N,N'-dipropyl-N,N'-diphenylurea, HPMBP = l-phenyl-3-methyl-4-benzoyl-pyrazolone-5) were synthesized and characterized. The coordination geometry of the uranyl atom in 1 is distorted hexagonal bipyramidal, coordinated by two oxygen atoms of two DPDPU molecules and four oxygen atoms of two bidentate nitrate groups. The coordination geometry of the uranyl atom in 2 is distorted pentagonal bipyramidal, coordinated by one oxygen atom of one DPDPU molecule and four oxygen atoms of two chelating PMBP molecules.
