With an inversion center at the mid-point of the two Re(III) atoms, the title compound, [Re2Cl2{O2C(CH2)2CH3}4], exhibits a paddle-wheel or lantern-type structure with four n-butyrate groups bridging two Re(III) atoms in a syn-syn fashion. The axial chloride ligands together with the Re-Re quadruple bond [2.2330 (3) Å] complete an essentially octa-hedral geometry around each Re(III) atom. There...
catena-Poly[[tetrakis(μ-pentafluorobenzoato-κ2 O:O′)dimolybdenum(II)]-μ-4,4′-bipyridine-κ2 N:N′]
In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain para...
The crystal structures and magnetic properties of two novel polyclusters {[Cu(3)(tci)(2)(H(2)O)(2)]·12H(2)O}(n) (1) and {[Cu(3)(tci)(2)(H(2)O)(2)]·6H(2)O}(n) (2) (tci = tris(2-carboxyethyl) isocyanurate) are investigated. The X-ray crystallographic analysis reveals that they contain interesting infinite alternating chains of dinuclear paddle-wheel copper and mononuclear copper units arranged in...
The complex mol-ecule of the title compound, [Cu(2)Fe(4)(C(5)H(5))(4)(C(6)H(4)O(2))(4)(CH(3)OH)(2)]·2CH(3)OH, lies about an inversion centre and contains two centrosymetrically related Cu(II) atoms bridged by four O:O'-bidentante ferrocene-carboxyl-ate anions, leading to a dimeric tetra-bridged unit with a paddle-wheel geometry. The Cu(II) atom has a distorted square-pyramidal coordination envi...
The central part of the title centrosymmetric dinuclear complex, [Zn(2)(C(7)H(5)O(2))(4)(C(9)H(12)N(2))(2)], has a paddle-wheel conformation with four benzoate ligands bridging two symmetry-related Zn(II) ions. The distorted square-pyramidal coordination environment around the Zn(II) ion is completed by an N atom from a 4-(pyrrolidin-1-yl)pyridine ligand. The Zn⋯Zn separation of 2.9826 (12) Å d...
A novel class of metal organic frameworks (MOFs) has been synthesized from Cu-acetate and dicarboxylic acids using liquid phase epitaxy. The SURMOF-2 isoreticular series exhibits P4 symmetry, for the longest linker a channel-size of 3 × 3 nm(2) is obtained, one of the largest values reported for any MOF so far. High quality, ab-initio electronic structure calculations confirm the stability of a...
The complete mol-ecule of the title complex, [Co(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The Co(II) ion is penta-coordinated by three O atoms from two 4-meth-oxy-benzoate anions (one bidentate and one monodentate) and two N atoms from two 2,2'-bis-(2-methyl-1H-benzimidazole)-ether ligands. This results in a ...
