A Chain Structure Based on Homodinuclear Scandium Units： Sc（μ-OH）（2,5-pydc）（H2O）n

摘要

cqvip:The reaction of pyridine-2,5-dicarboxylic acid with Sc2O3 under hydrothermal condition yields a new complex [Sc(μ-OH)(2,5-pydc)(H2O)]n 1 which has a chain structure based on homodinuclear scandium units. Crystal data for 1: space group P1, a = 6.7192(13), b = 7.6131(13), c = 8.9313(14) , α = 95.976(6), β = 101.663(6), γ = 108.151(5)°, V = 418.26(13) 3, Z = 2, Dc = 1.946 g/cm3 , μ = 0.889 mm-1, F(000) = 248, C7H6NO6Sc, Mr = 245.09, the final R = 0.0429 and wR = 0.1086.
