Supramolecular Isomerism in Cadmium Hydroxide Phases. Temperature-Dependent Synthesis and Structure of Photoluminescent Coordination Polymers of α- and β-Cd2(OH)2(2,4-pyda)

Two isomeric inorganic−organic hybrid materials formulated as [Cd 2 (OH) 2 (2,4-pyda)] (2,4-pyda = 2,4-pyridinedicarboxylate) have been hydrothermally synthesized via transformation of one-dimensional coordination chains formulated as [Cd(H 2 O) 2 (2,4-pyda)] into three-dimensional coordination polymers at different temperatures and characterized by crystallography.
