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 [NiL 2 ( i -C 3 H 7 OH) 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 [NiL 2 ( i -C 3 H 7 OH) 2 ] crystals leads to their spontaneous transformation into [NiL 2 (H 2 O)]· i -C 3 H 7 OH crystals whose structure is described in the present paper.
