TLDR
In this article, a general assignment of their vibrational (IR and Raman) spectra, compatible with the structural characteristics, is proposed, and the thermal behavior of both complexes is investigated by means of TG and DTA methods.Abstract:
Die Kristallstrukturen von [Co(Urocan)2(H2O)4] und [Zn(Urocan)2(H2O)4] (Urocan = Anion der Imidazol-4-acrylsaure = Urocaninsaure) wurden rontgenographisch an Einkristallen bestimmt. Sie sind isostrukturell und kristallisieren in der monoklinen Raumgruppe P21/c mit Z = 2. Eine Zuordnung ihrer Schwingungsspektren (IR und Raman), die mit den strukturellen Eigenschaften im Einklang steht, wird vorgeschlagen. Das thermische Verhalten beider Komplexe wurde an Hand von TG- und DTA-Messungen untersucht.
Crystal Structure, Vibrational Spectra, and Thermal Behavior of the Cobalt(II) and Zinc(II) Complexes of Urocanic Acid
The crystal structures of [Co(Urocan)2(H2O)4] and [Zn(Urocan)2(H2O)4] (urocan = anion of 4-imidazoleacrylic acid = urocanic acid) have been solved by single-crystal X-ray diffractometry. They are isostructural and crystallize in the monoclinic space group P21/c with Z = 2. A general assignment of their vibrational (IR and Raman) spectra, compatible with the structural characteristics, is proposed. The thermal behavior of both complexes was investigated by means of TG and DTA methods.read more

Crystal structures of metal-peptide complexes.
TL;DR: This chapter illustrates that, the existence of cis-trans isomers coordination isomers, optical isomer, and dimeric species in the crystalline complexes emphasizes the variety of species, which must be considered when equations are written to represent metal–peptide equilibria in solution.
