Direct synthesis and crystal structure of a novel tetranuclear Co2IIIFe2III Schiff base complex Chygorin, Eduard Nikolaevich Kokozay, Vladimir Nikolayevich Omelchenko, Iryna Vasylivna Rusanova, Julia Anatoliyivna Iron Cobalt Schiff base Direct synthesis Crystal structure Heterometallic complexes The title compound, tetra(µ-2-3-(2-oxybenzylideneamino)-1-hydroxypropan-2-olato)-4-nitrophenolatedi-cobalt(III)-di-iron(III) dimethylsulfoxidehexasolvate, crystallizes in the monoclinic space group P21/c and represent the first example of heterometallic CoIII-FeIII complex with 3-((5-nitro-2-hydroxybenzylidene)amino)propane-1,2-diol/2-(((2,3-dihydroxy propyl)iminio)methyl)-4-nitrophenolate) - a hydroxyl rich Schiff base ligand which was obtained in situ. Crystal data for C52H74Cl2Co2Fe2N8O26S6 (M = 1720.01 g/mol): monoclinic, space group P21/c (no. 14), a = 16.353(3) Å, b = 15.234(2) Å, c = 15.201(3) Å, β = 113.99(2)°, V = 3460.0(12) Å3, Z = 2, T = 173(2) K, μ(MoKα) = 1.225 mm-1, Dcalc = 1.651 g/cm3, 14130 reflections measured (5.7° ≤ 2Θ ≤ 57.266°), 7748 unique (Rint = 0.1051, Rsigma = 0.2148) which were used in all calculations. The final R1 was 0.0914 (I > 2σ(I)) and wR2 was 0.2279 (all data). The metal ions have distorted octahedral coordination geometry and are joined in a tetranuclear {Co2Fe2(µ-O)6} core by O-bridging atoms from the ligand. There are numerous intermolecular interactions occurring between the components of the crystal: π-hole interaction between NO2···NO2 groups of the ligands, short S···S, O···O and C··· C interactions and weak and strong hydrogen bonds.
