@article { , title = {Polymorphism in metal complexes of thiazole-4-carboxylic acid}, abstract = {Five new molecular complexes of chemical formula [M(4-tza)₂(H₂O)₂] (M = Co, Ni, and Cu) and a complex of [Cu(4-tza)₂]∙4H₂O using thiazole-4-carboxylic acid (4-tza) as the ligand have been successfully synthesized and structurally characterized by single crystal X-ray diffraction. Two district polymorphs (α and β) are found for both [Co(4-tza)₂(H₂O)₂] and [Ni(4-tza)₂(H₂O)₂]. The effects of solvent composition and temperature on the formation of these polymorphs have been investigated and phase behaviour of the polymorphs was studied through X-ray powder diffraction. Unlike two complexes of Co and Ni, [Cu(4-tza)₂(H₂O)₂] does not display polymorphism but exhibits irreversible structural transformation from [Cu(4-tza)₂(H₂O)₂] to the dehydrated form, [Cu(4-tza)₂], upon heating.}, doi = {10.1007/s11243-016-0079-7}, eissn = {1572-901X}, issn = {0340-4285}, issue = {7}, journal = {Transition metal chemistry}, pages = {783-793}, publicationstatus = {Published}, publisher = {Springer Verlag}, url = {https://hull-repository.worktribe.com/output/440626}, volume = {41}, keyword = {Specialist Research - Other, Thiazole-4-carboxylic acid, Crystal structure, Nickel, Cobalt, Copper, Polymorph}, year = {2016}, author = {Meundaeng, Natthaya and Rujiwatra, Apinpus and Prior, Timothy J.} }
