Magneto-structural correlations in dinuclear Mn(III) compounds with formula [{Mn(L)(NN)}(μ-O)(μ-2-RC6H4COO)2{Mn(L')(NN)}]n+.
Three dinuclear Mn(III) compounds with oxo and carboxylato bridges have been synthesized and characterized by X-ray diffraction: [{Mn(L)(NN)}(μ-2-ClC(6)H(4)COO)(2)(μ-O){Mn(L')(NN)}](n+) with NN = 2,2'-bipyridine (1 and 2) or 1,10-phenanthroline (3). The counteranion is either NO(3)(-) (1 and 3) or ClO(4)(-) (2) and the monodentate positions (L, L') could be occupied by molecules of water or the...
متن کامل{μ-trans-N,N′-Bis[2-(2-hydroxyethylamino)ethyl]oxamidato(2−)}bis[picratonickel(II)]
The title complex, [Ni(2)(C(6)H(2)N(3)O(7))(2)(C(10)H(20)N(4)O(4))], contains a centrosymmetric binuclear unit in which the oxamide ligand (located on a centre of symmetry) acts in a bis--tetra-dentate fashion and the picrate anion binds to nickel(II) in a bidentate mode. The Ni(II) atom displays a distorted octa-hedral coordination with axial elongation. The binuclear mol-ecules are linked by ...
متن کاملTetra-μ-benzoato-bis{[trans-1-(2-pyridyl)-2-(4-pyridyl)ethylene]zinc(II)}
The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(12)H(10)N(2))(2)], contains four bridging benzoate groups and two terminal trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene (L) ligands. The inversion center is located between the two Zn(II) atoms. The octa-hedral coordination around the Zn(II) atom, with four O atoms in the equatorial plane, is completed by a...
متن کاملNew insights into the comprehension of the magnetic properties of dinuclear Mn(III) compounds with the general formula [{MnL(NN)}2(μ-O)(μ-n-RC6H4COO)2]X2.
Five new dinuclear Mn(iii) compounds with benzoato derivative bridges [{Mn(bpy)L}2(μ-O)(μ-n-RC6H4COO)2]X2 (n-R = 3-MeO, 4-MeO and 4-tBu, X = NO3(-) and ClO4(-)) were synthesised and characterised. According to X-ray diffraction, the X anions tend to be coordinated to the Mn ions and may occupy the place of the monodentate ligand L. Two structural isomers that only differ in one of their monoden...

In the crystal structure of the title compound, [Fe(3)(NCS)(6)(C(4)H(4)N(2))(8)](n), each iron(II) cation is coordinated by four N-bonded pyrimidine ligands and two N-bonded thio-cyanate anions in a distorted octa-hedral environment. The asymmetric unit consists of one iron cation located on a crystallographic center of inversion, as well as one iron cation, three thio-cyanate anions and four p...
