چکیده
The title dimeric zirconium complex, [Zr(2)(C(20)H(24))(2)S(2)]·C(7)H(8), was obtained from the reaction of (ebthi)Zr(η(2)-Me(3)Si-C(2)-SiMe(3)) [ebthi is rac-1,2-bis-(η(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each Zr(IV) atom is coordinated by the sterically hindered ebthi ligand and two μ-sulfide ligands in a strongly distorted tetra-hedral geometry. The [ZrS](2) unit is almost planar (mean deviation from the best plane of the four atoms = 0.025 Å). A -CH(2)-CH(2)- group in one ebthi ligand was disordered over two sites, with refined occupancy factors of 0.551 (6) and 0.449 (6). The asymmetric unit also contains a toluene solvent mol-ecule.

The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are lo...

The coordination geometry of the Zn(II) atom in the title complex, [Zn(2)(NO(2))(4)(C(6)H(8)N(6))(2)], is distorted octa-hedral, in which the Zn(II) atom is coordinated by two N atoms from the triazole rings of two symmetry-related 1,2-bis-(1,2,4-triazol-4-yl)ethane ligands and four O atoms from two nitrite ligands. Two Zn(II) atoms are bridged by two organic ligands, forming a centrosymmetric ...

In the title compound, [Mn(C6H6O4)(C12H12N2)(H2O)] n , the cyclo-butane-1,1-di-carboxyl-ate (cbdc) ligands bridge three Mn(II) ions, forming layers parallel to the ac plane. These layers are additionally connected by 1,2-bis-(pyridin-4-yl)ethane ligands to form a three-dimensional polymeric framework. An inversion centre is located at the mid-point of the central C-C bond of the 1,2-bis-(pyridi...
