Two concomitant polymorphs of monomeric nickel acetate with 2-pyridineethanol.
A new mononuclear nickel(II) acetate with 2-pyridineethanol, Ni(ac)2(2-PyEtOH)2 has been prepared. The reaction product is a mixture of two polymorphic forms that crystallize concomitantly: triclinic (PĪ) and monoclinic (P21/c). Their structures have been determined at 150 K. The molecular structure of the mononuclear complex shows similar geometry in both polymorphic structures but they differ notably in the arrangement of mononuclear entities in space. The crystal densities are significantly different, nevertheless they behave as concomitant polymorphs.
