| Description | Lanthanide nitrates and bis(diphenylphosphino)hexane dioxide (dpphO2) formed under solvothermal conditions a series of coordination polymers [Ln(dpphO2)2(NO3)2](NO3) (Ln = Pr (1), Nd (2), Sm (3), Dy (4), Lu (5)), featuring two-dimensional network structure of the (4, 4) topology. The compounds [Ln(dpphO2)2Cl2]Cl (Ln = Pr (6), Nd (7), Gd (8)) were obtained from corresponding chlorides. Coordination polymer 7 formed regular single crystals of the orthorhombic Pna21 space group. The nitrate complexes crystallized in the orthorhombic Aea2 space group, however, the crystals were pseudo-merohedral twins simulating a tetragonal diffraction pattern. Unlike our previously characterized neutral polymers with bis(diphenylphosphino)ethane dioxide, all present coordination networks are cationic, with anions located between or within the two-dimensional layers. |
