Sažetak
Heating of cis aquabis(L-valinato)copper(II) powder at 90 °C and its subsequent recrystallization from aqueous solutions yielded anhydrous trans bis(L- valinato)copper(II). To resolve if heating affected the structural changes that steered the crystallization process, conformational analyses were performed for cis- and trans- conformers in vacuo and in crystal by molecular mechanics calculations using the same force field FFWa-SPCE [1]. Trans-conformers were calculated to be the most stable in vacuo, but cis- conformers form more favorable intermolecular interactions. The unit cell packing predictions suggest that cis-isomer requires water molecules to form energetically more stable crystal lattice packings than trans- isomer. On the other side, trans-isomer prefers anhydrous crystal packing. These predictions are in accordance with their X- ray molecular and crystal structures. [1] J. Sabolović, V. Gomzi, J. Chem.
