Catena-Poly[[(2-methyl-benzoato-?O,O')sodium]-di-?-aqua-?O:O'].

ABSTRACT: In the title coordination polymer, [Na(C(8)H(7)O(2))(H(2)O)(2)](n), the cation is chelated by the carboxyl-ate O atoms of the anion in a bidentate mode and is surrounded by the O atoms of four water mol-ecules. The coordination of the Na(+) cation is distorted octa-hedral. The water mol-ecules bridge adjacent metal cations, forming polymeric layers parallel to (100). The structure is stabilized by an extensive network of O-H?O hydrogen bonds.

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.

catena-Poly[[aqua-(3-methyl-benzoato-?O,O')lead(II)]-?-3-methyl-benzoato-?O:O,O':O'].

Project description:The reaction of lead(II) acetate and 3-methyl-benzoic acid (MBA) in aqueous solution yielded the title polymer, [Pb(C(8)H(7)O(2))(2)(H(2)O)](n). The asymmetric unit contains two Pb(II) atoms, four MBA ligands and two water mol-ecules. Each Pb(II) cation is hepta-coordinated and chelated by four carboxyl-ate O atoms from two MBA ligands. The Pb atoms are bridged through the carboxyl-ate O atoms from another two MBA ligands, leading to a central Pb(2)O(2) core. The Pb-O bond lengths are in the range 2.325?(3)-2.757?(4)?Å. The intra- and inter-dimer Pb?Pb distances are 4.2942?(3) and 4.2283?(3)?Å, respectively, indicating little direct metal-metal inter-action. The coordinating water mol-ecules and carboxyl-ate O atoms are involved in extensive O-H?O hydrogen-bonding inter-actions. The complex has an extended ladder-like chain structure and the chains are assembled by hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.6246?(3)?Å] into a three-dimensional supra-molecular structure.

Project description:In the title complex, {[NaNi(C(9)H(2)NO(8))(H(2)O)(7)]·4H(2)O}(n), the Ni(II) atom has a distorted octa-hedral coordination, defined by five O atoms from five water mol-ecules and one O atom from one 5-nitro-benzene-1,2,3-tricarboxyl-ate ligand. The Na cation is coordinated by six water O atoms in an irregular trigonal-prismatic geometry. There are seven coordinated water mol-ecules in the asymmetic unit. The Ni and Na atoms are linked by water bridges, forming infinite chains, which are connected by strong O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules into a three-dimensional network.

catena-Poly[[di-aqua-bis-(4-formyl-benzoato-?O (1))copper(II)]-?-pyrazine-?(2) N:N'].

Project description:In the title polymeric compound, [Cu(C8H5O3)2(C4H4N2)(H2O)2] n , the Cu(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination sphere. In the equatorial plane, it is coordinated by two carboxyl-ate O atoms of two symmetry-related monodentate formyl-benzoate anions and by two N atoms of the bridging pyrazine ligand, which is bis-ected by the twofold rotation axis. The axial positions are occupied by two O atoms of the coordinating water mol-ecules. In the formyl-benzoate anion, the carboxyl-ate group is twisted away from the attached benzene ring by 6.2?(2)°, while the benzene and pyrazine rings are oriented at a dihedral angle of 68.91?(8)°. The pyrazine ligands bridge the Cu(II) cations, forming polymeric chains running along the b-axis direction. Strong intra-molecular O-H?O hydrogen bonds link the water mol-ecules to the carboxyl-ate O atoms. In the crystal, O-Hwater?Owater hydrogen bonds link adjacent chains into layers parallel to the bc plane. The layers are linked via C-Hpyrazine?Oform-yl hydrogen bonds, forming a three-dimensional network. There are also weak C-H?? inter-actions present.

catena-Poly[[aqua-(2-iodo-benzoato-?O)cobalt(II)]-?-aqua-?-2-iodo-benzoato-?(2)O:O'].

Project description:The asymmetric unit of the polymeric title compound, [Co(C(7)H(4)IO(2))(2)(H(2)O)(2)](n), contains one Co(II) cation, two iodo-benzoate anions and two water mol-ecules. One iodo-benzoate anion and one water mol-ecule bridge adjacent Co cations, forming a polymeric chain running along the a axis, while the other iodo-benzoate anion and water mol-ecule coordinate in a monodentate manner to the Co(II) cation, completing the slightly distorted octa-hedral geometry. In the two independent anionic ligands, the carboxyl-ate groups are twisted away from the attached benzene rings by 51.38?(18) and 39.89?(11)°, and the two benzene rings are nearly perpendicular to each other with a dihedral angle of 86.09?(10)°. Intra-molecular O-H?O hydrogen bonds between coordinating water mol-ecules and adjacent carboxyl-ate O atoms help to stabilize the mol-ecular structure. In the crystal, weak C-H?O hydrogen bonds link the polymeric chains into a three-dimentional supra-molecular network.

catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

Project description:The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

catena-Poly[sodium-di-?-aqua-sodium-bis[?-2,2,2-trichloro-N-(dimorpholinophosphoryl)acetamide]].

Project description:The title compound, [Na(2)(C(10)H(16)Cl(3)N(3)O(4)P)(2)(H(2)O)(2)](n), can be considered as a two-dimensional coordination polymer in which one-dimensional chains are connected to each other by inter-molecular C-H?O hydrogen bonds involving the water mol-ecules. The Na(I) ion is five-coordinated in a distorted trigonal-bipyramidal geometry. The connection between the two Na(I) ions is facilitated by the two ?-O atoms of the carbonyl group of the 2,2,2-trichloro-N-(dimorpholino-phosphor-yl)acetamide (CAPh) ligand. A bridging coordination of the CAPh ligand via the carbonyl O atom is observed for the first time. The bridging water mol-ecules form inter-molecular O-H?O hydrogen bonds with the O atoms of the morpholine rings and the phosphoryl groups of neighboring CAPh mol-ecules.
