Synthesis and Crystal Structure of Poly{diaquaN-(2-hydroxybenzyl)-D,L- aspartatecadmium(II)}

摘要

The title compound, [Cd(C11H11NO5)(H2O)2]n, crystallizes in orthorhombic, space group Pbca with a = 8.521(3), b = 10.154(3), c = 28.804(8) (A), V = 2492.2(13) (A)3, Z = 8, C11H15NO7Cd, Mr = 385.64, Dc = 2.056 g/cm3, F(000) = 1536, μ(MoKα) = 1.786 mm-1, the final R = 0.0424 and wR = 0.0859 for 2026 observed reflections with I > 2σ(I). It has a one-dimensional zig-zag chain structure along the a axis driven by Cd-O coordination bonds. Three kinds of hydrogen bonds connect the chains along the b axis into a two-dimensional structure.
