Abstract: 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-HO and O-HN 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).
