Structure of A Ni(Ii) Mixed Ligand Complex with 3-Imidazoline Nitroxide, ISO-Propanol, and Water

A mixed ligand complex of Ni(II) with 3-imidazoline nitroxide and iso-propanol [NiL2(i-C3H7OH)2] is sensitive to atmospheric moisture. It is determined that at a high humidity, the air contacts with the mother solution of the compound in iso-propanol with the precipitated [NiL2(i-C3H7OH)2] crystals leads to their spontaneous transformation into [NiL2(H2O)]·i-C3H7OH crystals whose structure is described in the present paper.
