چکیده
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 inter-stitial water mol-ecules [qcq(-) is the N-(quinolin-8-yl)quinoline-2-carboxamidate anion and teta is 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne]. In the complex mol-ecule, 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 Ni(2+) cation lying on an inversion centre. The two inter-stitial water mol-ecules 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).

The two Ni(II) atoms in the title complex, [Ni(2)(CN)(4)(C(16)H(36)N(4))]·C(3)H(7)NO·0.5H(2)O, are bridged by a cyanide ion. The macrocycle folds around one Ni(II) atom, which is five-coordinated in an NiN(5) square-pyramidal geometry. The other Ni(II) atom is surrounded by the cyanide ions in an NiN(4) square-planar geometry. The dimethyl-formamide solvent mol-ecule is disordered over two posi...
