Three polymorphic phases have been found, all of them sharing the same molecular unit, the paddle-wheel, which grows forming a 1D coordination polymer or catena. The three polymorphs are defined by a different packing of these catenae and a specific arrangement of the alkyl chains. Ten new crystal structures of those compounds have been solved by high resolution powder diffraction and presented in this manuscript. The polymorphism in this series has been found to be monotropic and is responsible for the complex thermal behavior observed. The most characteristic feature, the endothermicexothermic effect, has been explained for the first time in these compounds by a combination of data from differential scanning calorimetry (in normal and modulated modes), powder Xray diffraction and Fourier transform infrared spectroscopy. These techniques, together with small angle X-ray scattering and optical microscopy, were used to analyze the hexagonal columnar discotic liquid crystal phase of copper(II) alkanoates. Thus, new information has been found in the packing and stacking of the discs formed by the paddle-wheel units, also maintained in the mesophase. eng New Advances in the One-Dimensional Coordination Polymer Copper(II) Alkanoates Series: Monotropic Polymorphism and Mesomorphism journal article URL https://docta.ucm.es/bitstreams/6ecebb99-2214-4a6e-aa5b-157666a8b77f/download File MD5 8b5d802b95144334efce2718c2b674dc 5491280 application/pdf New Advances in the One-Dimensional.pdf URL https://docta.ucm.es/bitstreams/047b9ec2-74cc-4024-9f77-729a7f47e1db/download File MD5 5a5369a8b156310dec079356bb5a950a 55597 text/plain New Advances in the One-Dimensional.pdf.txt
