Six dinuclear ferrous complexes including [Fe2(acpypentO)(O2CMe)(NCS)2] (1), [Fe2(acpypentO)(O2CMe)(NCSe)2] (2), [Fe2(acpypentO)(NCO)3] (3), ([Fe2(acpybutO)(O2CMe)(NCS)2] (5), [Fe2(acpybutO)(O2CMe)(NCO)2] (6), and [Fe2(acpybutO)(O2CMe)(N3)2] (7), one tetranuclear (bis-dinuclear) ferrous compound, [Fe4(acpypentO)2(N3)6] (4), and one mononuclear ferrous compound, [Fe(acpybutOH)(NCS)2] (8), have b...
We show that a dinuclear assembly apparently providing the first example of a synthetic molecule exhibiting key features of the diiron subsite of [FeFe] hydrogenase, viz. CO-bridging of a coordinatively unsaturated, dithiolate-bridged mixed-valence diiron centre, is in fact a diamagnetic tetranuclear complex.
The title compound, [Li(C(5)H(4)N(3)O(2))(H(2)O)](n), is composed of centrosymmetric dinuclear units, in which the Li(I) ions are bridged by two carboxyl-ate O atoms donated by two ligands. The dinuclear unit is nearly planar [r.m.s. deviation = 0.0125 (2) Å]. The Li(I) ion is coordinated by an N,O-chelating ligand, a bridging carboxyl-ate O atom from another ligand and two bridging water O ato...
The title compound {[Cu(2)Ho(2)(C(4)H(5)O(2))(10)(H(2)O)(4)]·3H(2)O}(n), is a one-dimensional 3d/4f organic-inorganic hybrid complex, the Ho(III) member of the isotypic lanthanoid series with Ln = Gd(III), Er(III) and Y(III). The structure shows an alternation of Cu(2) and Ho(2) dinuclear units bridged by the ligands and hydrogen bonds only. The chains are composed of Cu(2) classical dinuclear ...
In the polymeric title compound, {[Mn(2)(SO(4))(2)(C(30)H(36)N(6))(H(2)O)(2)]·6H(2)O}(n), the two Mn(2+) ions are bridged by two sulfate anions to form dinuclear complexes, and these dinuclear species are linked by the hexa-dentate ligand N,N,N',N'-tetra-kis(2-pyridylmeth-yl)hexane-1,6-diamine (tphn), forming a one-dimensional chain structure running in the [101] direction. The repeat unit of t...
New dinuclear carboranylcarboxylate-bridged and mononuclear copper(ii) compounds containing the 1-CO2H-2-H-1,2-closo-C2B10H10 carborane ligand () have been synthesized from the previously synthesized dinuclear compound [Cu2(μ-L)4(THF)2], . Reaction of with CuSO4 in THF leads to the dinuclear compound [Cu2(μ-L)4(THF)2], . The reaction of with different terminal pyridyl ligands leads to the forma...
