Demetallation of a Ni(II) tetraazamacrocyclic complex by cyanoxime resulting in the formation of a stereospecific trinuclear compound [Na(H2O)6]+[NaNi2L6]- (L = NC-C(NO)-C(O)NH[image omitted]) |

The reaction between the NiA(ClO4)2 and NaHL2 {where A = 14ane[N4], the macrocyclic ligands derived from the product of template condensation of 2,6-diacetylpyridine with aliphatic 3,3'-diaminodipropylamine, NH2(CH2)3NH(CH2)3NH2; and L = 2-cyano-2-isonitrosoacetamide anion, ACO- (amidecyanoxime, NC-C(NO)-C(O) [image omitted])} has led to the formation of a highly unusual trimetallic bis-[ fac-(triscyanoximato) nickel(II)] anionic complex anion instead of the expected Ni(II) macrocyclic complex with coordinated cyanoxime ligands. Two equivalent and symmetric trigonal-prismatic NiL [image omitted] units are connected to form the [NaNi2L6]- anion by the presence of a central sodium cation. The latter is located between two NiL [image omitted] anions and has an octahedral NaO6 geometry comprised of oxygen atoms of the nitroso group of the cyanoxime ligand. The oxime ligand is planar and adopts a cis-anti configuration in the complex. |
