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.

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.

Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chloro-phenyl-acetato ligand, forming a chain structure.

catena-Poly[[aqua-(4-ethyl-benzoic acid-κO)lanthanum(III)]-tri-μ-4-ethyl-benzoato].

Project description:The reaction of lanthanum nitrate and 4-ethyl-benzoic acid (EBAH) in aqueous solution yielded the title polymer, [La(C(9)H(9)O(2))(3)(C(9)H(10)O(2))(H(2)O)](n). The asymmetric unit contains one La(III) atom, three 4-ethyl-benzoate (EBA) ligands, one neutral EBAH ligand and one coordinated water mol-ecule. Each La(III) ion is eight-coordinated by six O atoms from six bridging-bidentate EBA ligands, one O atom from a monodentate EBAH ligand and one water O atom in a distorted bicapped trigonal-prismatic geometry. The adjacent La(III) ions are linked by the carboxyl-ate groups of EBA ligands in a bridging-bidetate coordination mode, resulting in an infinite chain structure along the c axis. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules, carboxyl-ate groups and carboxyl H atoms are formed within the one-dimensional polymer. One of the ethyl groups is disordered over two positions with occupancies of 0.717 (7) and 0.283 (7).

Crystal structure of catena-poly[[[di-aqua-bis-(2,4,6-tri-methyl-benzoato-κO)cobalt(II)]-μ-aqua-κ2O:O] dihydrate].

Project description:The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O} n , contains one CoII cation situated on a centre of inversion, one-half of a coordinating water mol-ecule, one 2,4,6-tri-methyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water mol-ecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxyl-ate group is twisted away from the attached benzene ring by 84.9 (2)°. The CoII atom is coordinated by two TMB anions and two water mol-ecules in the basal plane, while another water mol-ecule bridges the CoII atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the CoII cation is a slightly distorted octa-hedron. The coordinating and bridging water mol-ecules link to the carboxyl-ate groups via intra- and inter-molecular O-H⋯O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water mol-ecules link to the carboxyl-ate groups and the coordinating water mol-ecules link to the non-coordinating water mol-ecules via O-H⋯O hydrogen bonds, enclosing R22(8) and R33(8) ring motifs. Weak C-H⋯O and C-H⋯π inter-actions may further stabilize the crystal structure.

There are inter-molecular O-H?O and weak C-H?O hydrogen bonds within the two-dimensional structure.
