Dihydronium bis(2,6-diaminopyridinium) tris(pyridine-2,6-dicarboxylato- κ³O,O′,N)-dysprosate(III) dihydrate

چکیده مقاله

The reaction of dysprosium(III) chloride with [H₂pyda] ²⁺-[pydc]^2- (pyda is 2,6-diaminopyridine and H ₂pydc is 2,6-pyridinedicarboxylic acid) in an aqueous solution leads to the formation of the title Dy^III complex, (H₅O ₂)(C₅H₈N₃)₂-[Dy(C ₇H₃NO₄)₃]·2H₂O. The Dy ion lies on a twofold rotation axis and is nine-coordinated with a distorted tricapped trigonal-prismatic geometry. The dihydronium cation (H ₅O₂)⁺ is located on a twofold axis, the longer O-H bond distance being 1.225 Å. © 2006 International Union of Crystallography Printed in Great Britain - all rights reserved.
