Poly[μ-aqua-μ5-[2-(2,3,6-tri-chloro-phenyl)acetato]-caesium].

ABSTRACT: In the structure of the title complex, [Cs(C8H4Cl3O2)(H2O)] n , the caesium salt of the commercial herbicide fenac [(2,3,6-tri-chloro-phen-yl)acetic acid], the irregular eight-coordination about Cs(+) comprises a bidentate O:Cl-chelate inter-action involving a carboxyl-ate-O atom and an ortho-related ring-substituted Cl atom, which is also bridging, a triple-bridging carboxyl-ate-O atom and a bridging water mol-ecule. A two-dimensional polymer is generated, lying parallel to (100), within which there are water-carboxyl-ate O-H⋯O hy-dro-gen-bonding inter-actions.

Poly[tri-μ-aqua-di-aqua-μ-phosphono-formato-cobalt(II)sodium].

Project description:The title complex, [CoNa(CO5P)(H2O)5]n, was obtained by reacting sodium phosphono-formate with cobalt nitrate. The complex contains cobalt(II) and sodium ions, which are bridged by the O atoms of two aqua ligands. The Co(II) ion is octahedrally coordinated by three phosphonoformato ligands (one bi- and the other monodentate) and by two O atoms from the bridging aqua ligands. The sodium cation is hexa-coordinated by six O atoms from four bridging and two terminal aqua ligands. The complex mol-ecules are linked to give a three-dimensional structure by phosphono-formate ligands bridging Co(II) atoms and water mol-ecules establishing cobalt-sodium bridges. O-H⋯O hydrogen bonding between the aqua ligands and all O atoms of the phosphono-formato ligand and neighbouring aqua ligands help to consolidate the packing.

Poly[potassium-μ-2-[2-(carboxymethyl)phenyl]acetato].

Project description:In the title salt, [K(C(10)H(9)O(4))](n), the K(+) ions are coordinated by six O atoms from three different anions, and there is a cation-π inter-action at ca 3.14 Å. The 2-[2-(carboxymethyl)phenyl]acetate anions are stabilized by intramolecular O-H⋯O hydrogen bonds, and the K(+) cations are linked into one-dimensional coordination polymers running along the b axis; these are further inter-connected by weak C-H⋯O hydrogen bonds.

Project description:In the title polymeric coordination compound, [Sn(CH(3))(3)(C(8)H(6)ClO(2))](n), the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxyl-ate O atoms of the 2-chloro-phenyl-acetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chloro-phenyl-acetato ligand, forming a chain structure.

Project description:In the title complex, [Cd(C(5)H(4)NO)(C(12)H(9)O(2))(H(2)O)](n), each Cd(II) atom is coordinated by two carboxylate O atoms from one 1-naphthyl-acetate ligand, two hydroxyl O atoms from two pyridin-3-olate ligands, one N atom from another pyridin-3-olate ligand and one water mol-ecule, and displays a distorted octa-hedral coordination geometry. The compound forms infinite chains of pyridin-3-olate ligands bridging 1-naphthyl-acetate-Cd(II) units parallel to the b axis, with a Cd⋯Cd separation of 3.578 (2) Å. The chains are further self-assembled into a supra-molecular network through inter-molecular O-H⋯O hydrogen-bonding inter-actions.

Project description:The crystal structure of the title compound, {[Na(C(7)H(5)ClNO(2))(H(2)O)(3)]·H(2)O}(n), features polymeric chains along [010]. The Na(+) cation is octa-hedrally coordinated by four bridging water mol-ecules, a terminal water mol-ecule and an O atom derived from a monodentate carboxyl-ate ligand. Adjacent polyhedra share two O?O edges. The polymeric chains are linked into a three-dimensional network via O-H?O and O-H?N hydrogen bonds.

Project description:In the title compound, [CuNa(3)(CH(3)CO(2))(5)(CH(3)COOH)(H(2)O)(2)](n), the Cu(II) atom lies on an inversion center and is coordinated by four O atoms from four acetate ligands, leading to a square-planar geometry. One Na(I) atom, lying on an inversion center, is coordinated by four O atoms from four acetate ligands and two bridging water mol-ecules in a distorted octa-hedral geometry. The other Na(I) atom is coordinated by five O atoms from five acetate ligands and a bridging water mol-ecule. A hy-droxy H atom lies on a twofold rotation axis and is shared by two acetate ligands. The crystal packing exhibits a polymeric layer parallel to (100), which is further stablized by intra-layer O-H⋯O hydrogen bonds. The layers are linked by inter-layer O-H⋯O hydrogen bonds.

Project description:In the title compound, [Cd(C4H5NO4)(H2O)2] n , the Cd(II) atom exhibits a distorted octa-hedral coordination geometry, defined by one N atom and three O atoms from two iminodi-acetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another Cd(II) atom, thus forming a zigzag chain along [001]. A three-dimensional network is completed by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

Poly[[aqua-tri-μ(3)-hydroxido-(μ(4)-2-phos-phon-ato-ethane-sulfonato)-dierbium(III)] monohydrate].

Project description:The crystal structure of the title compound, {[Er(2)(C(2)H(4)O(6)PS)(OH)(3)(H(2)O)]·H(2)O}(n), consists of two Er(3+) ions, one (C(2)H(4)O(6)PS)(3-) ion, three OH(-) ions, and two water mol-ecule. The Er(3+) ions form ErO(8) polyhedra., which are connected by μ- and μ(3)-O atoms. Thus, inorganic Er-O-Er layers of edge- and face-sharing polyhedra are observed. Whereas most often in metal phosphono-sulfonates the organic linker bridges adjacent layers, in the title compound, the (O(3)PC(2)H(4)SO(3))(3-) anion is only connected to one Er-O-Er layer. Short interatomic O⋯O distances [2.898 (8), 2.997 (14) and 2.768 (10) Å] indicate hydrogen bonding between the layers. The noncoordinated water mol-ecules are located between the layers.
