چکیده
The title compound, [Hf(3)(C(6)H(7))(6)Cl(2)O(2)], is a trinuclear mol-ecule having two (MeCp)(2)HfCl units (MeCp is methyl-cyclo-penta-dien-yl) each connected to an (MeCp)(2)Hf unit by an oxide bridge. The two Hf-O-Hf bridges are nearly linear. The geometry of the three Hf atoms is tetra-hedral (assuming the MeCp group occupies one coordination site); the O-Hf-O angle is 99.8 (5)°. One of the Cl atoms is disordered, with site occupancies of 0.61 (7) and 0.39 (7).

The title compound, [Zr₃(C₅H₅)₆Cl₂O₂], exists as discrete mol-ecules possessing a series of three Cp(2)Zr units (Cp is cyclo-penta-dien-yl) bridged by oxide ligands and end-capped by chloride ligands. The Cp planes in the central and terminal zirconocene units form dihedral angles of 53.3 (2) and 53.5 (2)°, respectively. The two Zr-O-Zr bridge angles are nearly linear and form a planar Zr₃O₂ co...

The title polynuclear organometallic titanium(IV) oxide, [{Ti3(η(5)-C5Me5)3(μ-O)4}2(μ-O)], exhibits two Ti3O4 cores bridged by an O atom located on a twofold axis. All metal centres present the typical three-legged piano-stool coordination environment, where one site is occupied by a penta-methyl-cyclo-penta-dienyl ligand linked in an η(5)-coordination fashion, while three bridging O atoms fill...

The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-...

In the centrosymmetric trinuclear Zn(II)⋯Ca(II)⋯Zn(II) title complex, [CaZn2(CH3COO)6(C12H12N2)2], the Ca(II) ion lies on an inversion centre and is octa-hedrally coordinated by six acetate O atoms. The Zn(II) ion is coordinated by two N atoms from a bidentate di-methyl-bipyridine ligand and three O atoms from acetate ligands bridging to the Ca(II) ion, leading to a distorted square-pyramidal c...
