Abstract:

Each Sc3+ ion in the title salt, di-μ-hydroxido-bis-[tri-aqua-(nitrato-κ2 O,O')scandium(III)] dichloride, [Sc2(NO3)2(OH)2(H2O)6]Cl2, is coordinated by a nitrate anion, two hydroxide ions and three water mol-ecules to generate a distorted penta-gonal-bipyramidal ScO7 coordination polyhedron. The complete {[(NO3)(μ-OH)Sc(H2O)3]2}2+ ion is generated by crystallographic inversion symmetry. The nitrate anion binds in a bidentate fashion whereas the hydroxide ions are bridged between two Sc centers. Two charge-balancing Cl- ions are located in the outer sphere. In the extended structure, O-H⋯O and O-H⋯Cl hydrogen bonds connect the components into a three-dimensional network.
