Sažetak
From the crystals of trans aquabis(N, N-dimethylglycinato-kN, kO)copper(II) dihydrate (compound 1, space group P212121) novel crystal structure of trans aquabis(N, N-dimethylglycinato-kN, kO)copper(II) (compound 2, space group Pbca) was obtained and analysed by X-ray diffraction. In the crystal structure 1, the O&#8211; H&#903; &#903; &#903; O hydrogen bonds form three-dimensional network. In the crystal structure 2, two-dimensional layers stacking to each other are formed, with non-polar N, N-dimethyl groups placed on the opposite sides of the layers, and with the polar part in the middle forming C=O&#903; &#903; &#903; O&#8211; H and C&#8211; H&#903; &#903; &#903; O hydrogen bonds. Different hydrogen bonding patterns in 1 and 2 do not pronouncedly affect molecular geometry of the title compound. Molecular mechanics force field suited for studying the properties of bis(amino acidato)copper(II) complexes in the solid state can follow the differences between the experimental molecular structures in the two diverse crystalline surroundings. To make possible direct comparison between crystal lattices, the force field was applied to predict unit cell packing of supposed anhydrous bis(N, N-dimethylglycinato)copper(II) in space group Pbca. Relative intermolecular energies of hypothetic anhydrous crystal and simulated 1 and 2 crystals are discussed. On the basis of experimental and theoretical results we conclude that the main effect of two water molecules of crystallisation in 1 is to stabilise the crystal packing via hydrogen bonding, whilst similar pyramidal copper(II) coordination geometry in 1 and 2 is due to axially coordinated water molecule and its intermolecular interactions.
