Di-μ-cyanido-tetra­cyanido(557121214-hexa­methyl-14811-tetra­aza­cyclo­tetra­decane)N-(quinolin-8-yl)quinoline-2-carboxamidatodiiron(III)nickel(II) 2.07-hydrate

摘要

The asymmetric unit of the title complex, [Fe2Ni(C19H12N3O)2(CN)6(C16H36N4)]·2.07H2O, contains one [Fe(qcq)(CN)3]⁻ anion, half a [Ni(teta)]²⁺ cation and two partially occupied inter­stitial water mol­ecules [qcq⁻ is the N-(quinolin-8-yl)quinoline-2-carboxamidate anion and teta is 5,5,7,12,12,14-hexa­methyl-1,4,8,11-tetra­aza­cyclo­tetra­deca­ne]. In the complex mol­ecule, two [Fe(qcq)(CN)3]⁻ anions additionally coordinate the central [Ni(teta)]²⁺ cation through cyanide groups in a trans mode, resulting in a trinuclear structure with the Ni²⁺ cation lying on an inversion centre. The two inter­stitial water mol­ecules are partially occupied, with occupancy factors of 0.528 (10) and 0.506 (9). O—H⋯O and O—H⋯N hydrogen bonding involving the two lattice water molecules and the carbonyl function and a teta N atom in an adjacent cluster leads to the formation of layers extending parallel to (010).
