The title compound, [Ti(C15H17NO2S)Cl2], has a Ti atom bound to the N and O atoms of a p‐toluenesulfonamide ligand, which is tethered by a three‐carbon chain to a η5‐cyclopentadienyl group. The distorted square‐pyramidal geometry is completed by two Cl atoms. The Ti—N bond length of 2.0375 (13) Å is longer than that in related compounds, the N atom having asymmetric trigonal–planar geometry. Conformational strain relief is noted when compared with ethyl‐tethered compounds. 相似文献

In the title compound, [In(C8H4O4)(OH)(H2O)]n, the coordination of the InIII ion is composed of six O atoms from three dianionic benzene‐1,2‐dicarboxylate ligands, two hydroxyl groups and one coordinated water molecule in a distorted octahedral geometry. The In3+ ions are linked by the hydroxyl groups to form zigzag In–OH–In chains, which are further bridged by the benzene‐1,2‐dicarboxylic acid ligands to generate a two‐dimensional layered structure featuring three types of rings (six‐, 14‐ and 20‐membered). Hydrogen bonds between the water molecule and a carboxylate O atom, and between the hydroxyl group and a carboxylate O atom, are observed within the layers. In the crystal packing, there are π–π stacking interactions between the benzene rings of adjacent layers, with a centroid‐to‐centroid distance of 3.668 (3) Å and a dihedral angle of 4.8 (2)°. 相似文献

The title nest‐shaped cluster, [Cu3WIOS3(C10H8N2)2], has been synthesized by the reaction of (NH4)2[WOS3], CuI and 2,2′‐bipyridine (bipy) in dimethylformamide under a purified nitrogen atmosphere. The cluster has a neutral skeleton containing the bipy ligands, and the central W atom is tetrahedrally coordinated by three S atoms and one O atom. The three Cu atoms are divided into two different kinds. Two Cu atoms adopt distorted tetrahedral geometry, with each Cu atom coordinated by two S atoms and the two N atoms of a bipy ligand. The other Cu atom adopts a trigonal mode surrounded by two S atoms and one I atom. 相似文献

Synthesis,structure and property of diorganotin N‐[(3‐methoxy‐2‐oxyphenyl)methylene]tyrosinates 下载免费PDF全文
Five new diorganotin N‐[(3‐methoxy‐2‐oxyphenyl)methylene] tyrosinates, R2Sn[2‐O‐3‐MeOC6H3CH=NCH (CH2C6H4OH‐4)COO] (R = Me, 1 ; Et, 2 ; Bu, 3 ; Cy, 4 ; Ph, 5 ), have been synthesized and characterized by elemental analysis, IR, NMR (1H, 13C and 119Sn) spectra, and the X‐ray single crystal diffraction. In non‐coordinated solvent, complexes 1 – 5 have penta‐coordinated tin atom. In the solid state, 1 – 3 are centrosymmetric dimmers in which each tin atom is seven‐coordinated in a distorted pentagonal bipyramid, and 4 displays discrete molecular structure with distorted trigonal bipyramidal geometry, and the tin atom of 5 is hexa‐coordinated and possess the distorted octahedral geometry with a coordinational methanol molecule. The intermolecular O‐H???O hydrogen bonds in 1 – 4 link molecules into the different one‐dimensional supramolecular chain with R22 (30) or R22 (20) macrocycles, and the molecules of 5 are joined into a two‐dimensional supramolecular network containing R44 (24) and R44 (28) two macrocycles. Bioassay results against human tumour cell HeLa indicated that 3 ‐ 5 belonged to the efficient cytostatic agents and the activity decreased in the order 4 > 3 > 5 > 2 > 1. The fluorescence determinations show the complexes may be explored for potential luminescent materials. 相似文献

In the title coordination polymer, [Cd2(SO4)2(C13H8N4)(H2O)2]n, there are two crystallographically independent CdII centres with different coordination geometries. The first CdII centre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H‐imidazo[4,5‐f][1,10]phenanthroline (IP) ligand, giving a distorted octahedral coordination environment. The second CdII centre is heptacoordinated by four O atoms of three sulfate ligands, one water O atom and two N atoms of one chelating IP ligand, resulting in a distorted monocapped anti‐trigonal prismatic geometry. The symmetry‐independent CdII ions are bridged in an alternating fashion by sulfate ligands, forming one‐dimensional ladder‐like chains which are connected through the IP ligands to form two‐dimensional layers. These two‐dimensional layers are linked by interlayer hydrogen bonds, leading to the formation of a three‐dimensional supramolecular network. 相似文献

In the title centrosymmetric binuclear complex, [Cu2(C14H11N2O3)2(H2O)2](NO3)2, the two metal centres are bridged by the phenolate O atoms of the ligand, forming a Cu2O2 quadrangle. Each Cu atom has a distorted square‐pyramidal geometry, with the basal donor atoms coming from the O,N,O′‐tridentate ligand and a symmetry‐related phenolate O atom. The more weakly bound apical donor O atom is supplied by a coordinated water molecule. When a further weak Cu...O interaction with the 4‐hydroxy O atom of a neighbouring cation is considered, the extended coordination sphere of the Cu atom can be described as distorted octahedral. This interaction leads to two‐dimensional layers, which extend parallel to the (100) direction. The two‐dimensional polymeric structure contrasts with other reported structures involving salicylaldehyde benzoylhydrazone ligands, which are usually discrete mono‐ or dinuclear Cu complexes. The nitrate anions are involved in a three‐dimensional hydrogen‐bonding network, featuring intermolecular N—H...O and O—H...O hydrogen bonds. 相似文献

In the three title complexes, namely (2,2′‐biquinoline‐κ2N,N′)dichloropalladium(II), [PdCl2(C18H12N2)], (I), and the corresponding copper(II), [CuCl2(C18H12N2)], (II), and zinc(II) complexes, [ZnCl2(C18H12N2)], (III), each metal atom is four‐coordinate and bonded by two N atoms of a 2,2′‐biquinoline molecule and two Cl atoms. The PdII atom has a distorted cis‐square‐planar coordination geometry, whereas the CuII and ZnII atoms both have a distorted tetrahedral geometry. The dihedral angles between the N—M—N and Cl—M—Cl planes are 14.53 (13), 65.42 (15) and 85.19 (9)° for (I), (II) and (III), respectively. The structure of (II) has twofold imposed symmetry. 相似文献

In the title molecular complex, [Cu4Cl6O(2‐EtTz)4], where 2‐EtTz is 2‐ethyltetrazole (C3H6N4), the central O atom is located on the symmetry site and is tetrahedrally coordinated to four Cu atoms, with Cu—O distances of 1.8966 (4) Å. A very slight distortion of Cu4O from a regular tetrahedron is observed [two Cu—O—Cu angles are 108.76 (3)° and four others are 109.828 (13)°]. Each Cu atom is connected to three others via the Cl atoms, forming a slightly distorted Cl octahedron around the O atom, with O⋯Cl distances of 2.9265 (7) Å for Cl atoms lying on the twofold axis and 2.9441 (13) Å for those in general positions. The Cu atom has a distorted trigonal–bipyramidal environment, with three Cl atoms in the equatorial plane, and with the N atom of the 2‐ethyltetrazole ligand and the μ4‐O atom in axial positions. The Cu atom is displaced out of the equatorial plane by ca 0.91 Å towards the coordinated N atom of the 2‐ethyltetrazole ligand. 相似文献

The title compound, [Mn(C14H8O4)(C12H12N2)]n, with a novel three‐dimensional framework, has been prepared by a hydrothermal reaction at 433 K. Each Mn atom lies on a twofold axis in a slightly distorted octahedral geometry, coordinated by two N atoms from two benzidine ligands and four O atoms from three symmetry‐related biphenyl‐2,2′‐dicarboxylate (bpdc) ligands. The benzidine ligands lie about inversion centres and the bpdc ligands about twofold axes. Each bpdc ligand is bonded to three Mn ions to form a continuous chain of metal ions. The bpdc ligands are accommodated in a series of distorted holes resembling hexagonal prisms. 相似文献

The title compound, [Cu2(OH)2(C12H8N2)2(H2O)2][Cu(C10H9NO5S)2]·6H2O, is comprised of a copper‐centred complex cation and a copper‐centred complex anion; the cation lies about an inversion centre and in the anion the Cu atom lies on an inversion centre. In the doubly charged bridged dicopper cation, each Cu centre has distorted square‐pyramidal geometry. In the square‐planar dianion, two sulfonate ligands are trans coordinated to the Cu atom via a deprotonated hydroxyl O atom and an imine N atom, forming two six‐membered chelate rings. The structure is stabilized by an extensive hydrogen‐bond system and aromatic‐ring stacking interactions. 相似文献

In the crystal structure of the title compound, [Cu(C2N3)2(C12H12N2)]n, the CuII atom adopts a distorted square‐pyramidal geometry, the basal plane of which is formed by two N atoms of the bipyridine ligand, one N atom of a bidentate dicyanamide anion and one N atom of a monodentate dicyanamide anion [Cu—N = 1.9760 (15)–2.0157 (15) Å]. The apical position is occupied by an N atom of a bidentate dicyanamide anion, located 2.2468 (16) Å from the Cu atom, thus forming a one‐dimensional polymeric chain. 相似文献

In the title coordination polymer, [Pb(NCS)2(C12H12N2)], the coordination geometry about the PbII atom is a distorted octahedron, composed of two N atoms from bpe ligands [bpe is 1,2‐bis(4‐pyridyl)ethane], two other N atoms from NCS? groups and two neighbouring S atoms through short contacts. The trans‐bpe ligands act as bridges between two PbII centres resulting in the formation of a linear chain. The terminal S atoms of the NCS? ligands make short contacts with the PbII atom of neighbouring chains to form an infinite two‐dimensional polymeric structure. 相似文献
