The title complex, [Sn(C6H5)3(C6H3ClNO2)(H2O)], is five-coordinate with a distorted trigonal–bipyramidal geometry in the solid state. The O atom of the carboxylate group occupies one of the axial sites and the O atom of the water molecule occupies the other. Water H atoms are involved in an intermolecular hydrogen-bonded network with the uncoordinated carboxylate O atom and the pyridine N atom; the interactions lead to two types of rings.

The ManganeseII Isovanillin complex [Mn2(C8H7O3)4(H2O)2], Diaqua-tetra (isovanillinato-O,O')-bis (manganeseII),the MnII atom is coordinated by three isovanillinate anions and one water molecule in a distorted trigonal bipyramidal configuration with five-coordinations geometry. And one isovanillinate ligand chelates to the MnII atom through its methyl and hydroxy O atoms, the other two isovanillinate ligand chelates to the MnII atom only through its hydroxy O atoms. The same as another MnII atom. So we get a Binuclear MnII metal complexe. The fact clearly suggests not so much significant contribution from the electrostatic interaction in the Mn-O bonding in Binuclear MnII metal complexes as we gotten in mononuclear MnII metal complexes. Adjacent complex link to each other via hydrogen bonds forming the three-dimensional supramolecular structure.

In the centrosymmetric binuclear title complex, [Cu2(C7H4IO2)4(H2O)2], the two CuIIions [Cu...Cu = 2.6009 (5) Å] are bridged by four 2-iodobenzoate (IB) ligands. The four nearest O atoms around each CuIIion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the O atom of the water molecule at a distance of 2.1525 (16) Å. The dihedral angle between the benzene ring and the carboxylate group is 25.67 (13)° in one of the independent IB ligands and 6.44 (11)° in the other. The benzene rings of the two independent IB ligands are oriented at a dihedral angle of 86.61 (7)°. In the crystal, O—H...O interactions link the molecules into a two-dimensional network. π–π contacts between the benzene rings [centroid–centroid distances = 3.810 (2) and 3.838 (2) Å] may further stabilize the structure.

A new mixed-amido complex (Me2N)3Ta(Cl)[N(SiMe3)2] (1) was prepared from the reaction of (Me2N)3TaCl2 with 1 equiv. of LiN(SiMe3)2. The reactions of 1 with 1 equiv. of LiN(SiMe3)2 or (Me2N)3TaCl2 with 2 equiv. of LiN(SiMe3)2 gave (Me2N)3[Formula: see text] (2) with a four-membered metallaheterocyclic ring through γ-hydrogen abstraction. In the solid state, 1 adopts a distorted trigonal bipyramidal geometry with the -N(SiMe3)2 and -Cl ligands in the equatorial and axial positions, respectively. The X-ray structure of 2 reveals that it is in a distorted trigonal bipyramidal geometry with a planar metallaheterocyclic ring.Key words: tantalum, γ-hydrogen abstraction, C-H activation, amido complexes, metallacycle.

In the title complex, [Cu2(C8Br4O4)2(C6H16N2)2(H2O)2], the CuIIcation is chelated by a tetramethylethane-1,2-diamine ligand and coordinated by a water molecule as well as bridged by two tetrabromophthalate anions in a distorted O3N2trigonal–bipyramidal geometry. The two symmetry-related tetrabromophthalate anions bridge the two CuIIcations, forming a centrosymmetric dinuclear complex in which the Cu...Cu separation is 5.054 (2) Å. Intramolecular classic O—H...O hydrogen bonds and weak C—H...O hydrogen bonds occur in the dinuclear molecule. In the crystal, the molecules are linked by weak C—H...Br and C—H...O interactions into supramolecular chains propagating along theb-axis direction.

The title compound, [Sn2Cl2(CH3)4(C6H5N2O2)2], forms infinite one-dimensional zigzag chains that propagate in a helical fashion along the c axis via an Sn—O=C—O—Sn—O bridge which involves the carboxylate groups of two methylpyrazinecarboxylate ligands. These display both chelating and bridging coordination behaviour. The asymmetric unit contains two Sn atoms; one adopts a distorted trigonal–bipyramidal geometry, while the other is in a distorted pentagonal–bipyramidal configuration.
