Poly[[?-aqua-tetraaquabis(?-2-hydroxy-4-oxocyclobut-1-ene-1,3-diolato)strontium] hemihydrate].

ABSTRACT: In the title coordination polymer, {[Sr(C(4)HO(4))(2)(H(2)O)(5)]·0.5H(2)O}(n), the Sr(2+) ion is coordinated by three monodentate hydrogensquarate (hsq) anions and six aqua ligands in a distorted SrO(9) monocapped square-anti-prismatic geometry. The hsq anions and water mol-ecules bridge the metal ions into infinite sheets lying parallel to (100). The O atom of the uncoordinated water mol-ecule lies on a crystallographic twofold axis. The packing is stabilized by numerous O-H?O hydrogen bonds.

Poly[?-aqua-?(4)-terephthalato-strontium].

Project description:In the title compound, [Sr(C(8)H(4)O(4))(H(2)O)](n), the Sr(II) atom exhibits coordination number eight, with six O atoms from four carboxylate groups (two bidentate and two monodentate) of terephthalate ligands and two water O atoms. The SrO(8) polyhedra are linked into inorganic chains by sharing three coplanar O atoms. These inorganic chains are extended along the b axis to form layers in the ab plane by O-C-O linking. Parallel layers are connected by terephthalic groups, forming a three-dimensional framework. O-H?O hydrogen-bonding inter-actions are observed.

Poly[?(2)-aqua-aqua-?(5)-naphthalene-2,7-disulfonato-strontium].

Project description:In the crystal structure of the polymeric title compound, [Sr(C(10)H(6)O(6)S(2))(H(2)O)(2)](n), the naphthalene-2,7-disulfonate dianion uses one -SO(3) unit to bind to two Sr(II) cations and the other -SO(3) unit to bind to three Sr(II) cations; of the two coordinated water mol-ecules, one is monodentate to one Sr(II) cation, whereas the other bridges two Sr(II) cations. The ?(5)-bridging mode of the dianon and the ?(2)-bridging mode of the water mol-ecule generate a polymeric three-dimensional network which is consolidated by O-H?O hydrogen bonds. The Sr(II) cation exists in an undefined eight-coordinate environment.

Project description:In the title polymeric coordination complex, {[Cd(C(22)H(20)N(2)O(6))(H(2)O)(4)](NO(3))(2)·0.5H(2)O}(n), obtained from the self-assembly of the flexible double betaine 3,3'-[p-phenyl-enebis(oxymethyl-ene)]bis-(1-pyridinioacetate) with cadmium nitrate, both the octa-hedrally coordinated Cd(II) cation and the substituted betaine ligand lie on inversion centres. The chains constructed through the trans-related acetate groups of the ligand are inter-connected via O-H?O hydrogen bonds involving coordinated aqua ligands, the nitrate anions and the partial-occupancy (0.25) water mol-ecule of solvation, forming a three-dimensional structure.

Poly[?(2)-aqua-aqua-?(4)-pyridine-2,4-dicarboxyl-ato-strontium].

Project description:In the title polymeric complex, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) atom is eight-coordinated by four O atoms and one N atom of four pyridine-2,4-dicarboxyl-ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol-ecules in a dodeca-hedral geometry. These units are connected via the carboxyl-ate O atoms and water mol-ecules, building polymeric layers parallel to (100). In the crystal structure, non-covalent inter-actions consisting of O-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.862?(17) and 3.749?(17)?Å] connect the various components, forming a three-dimensional structure.

Project description:The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353?(8):0.647?(8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that propagate along the b axis. Inter- and intra-molecular O-H?O hydrogen bonds maintain the crystal packing through a three-dimensional network.

catena-Poly[[[tetra-aqua-magnesium]-trans-?-[(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nato] hemihydrate].

Project description:The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of the corners of the MgO6 polyhedra and bind to the O atoms of the phospho-nate groups of neighbouring chains. The lattice water molecule is disordered around an inversion centre, exhibiting an occupancy of 0.25.

catena-Poly[[[aqua-(1,10-phenanthro-line)zinc(II)]-?-3,3'-(p-phenyl-ene)di-acrylato] hemihydrate].

Project description:In the title compound, {[Zn(C(12)H(8)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5H(2)O}(n), each Zn(II) atom is six-coordinated by two N atoms from one 1,10-phenanthroline (phen), three carboxyl-ate O atoms from two different L ligands [H(2)L = 3,3'-(p-phenyl-ene)diacrylic acid] and one water mol-ecule in a distorted octa-hedral environment. The two L dianions are situated across inversion centres and bridge neighbouring Zn(II) centres, yielding a chain propagating parallel to [100]. O-H?O hydrogen bonds between the coordinated water molecule, the solvent water molecule (half-occupied) and the carboxylate O atoms further stabilize the structure.

Poly[tetra-aqua-?(3)-pyridine-3,5-dicarboxyl-ato-strontium(II)].

Project description:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol-ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca-hedron. These binuclear units are connected via the carboxyl-ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter-actions consisting of hydrogen bonds (X-H?O, with X = O and C) and ?-? stacking inter-actions [3.4604?(19)?Å] connect the various components to form a supra-molecular structure.

Poly[[aqua-tris-(?(4)-benzene-1,2-dicarboxyl-ato)dilanthanum(III)] hemihydrate].

Project description:The asymmetric unit of the title coordination polymer, {[La(2)(C(8)H(4)O(4))(3)(H(2)O)]·0.5H(2)O}(n), contains two independent La(III) atoms, one of which is surrounded by eight carboxyl-ate-O atoms from six benzene-1,2-dicarboxyl-ate (BDC) anions in a bicapped trigonal-prismatic geometry. The other La(III) atom is nine-coordinated in a tricapped trigonal-prismatic geometry, formed by eight carboxyl-ate-O atoms from six BDC anions and a coordinated water mol-ecule. The BDC anions bridge the La(III) atoms, forming a two-dimensional polymeric complex parallel to (001). The crystal structure contains weak O-H?O and non-classical C-H?O hydrogen bonds. A C-H?? inter-action is also present in the crystal structure. The uncoordinated water molecule shows half-occupation.
