Poly[[tetra-aqua-(?(3)-naphthalene-1,6-disulfonato-?O:O,O:O)strontium(II)] monohydrate].

ABSTRACT: In the crystal structure of the polymeric title compound, {[Sr(C(10)H(6)O(6)S(2))(H(2)O)(4)]·H(2)O}(n), the naphthalene-1,6-disulfonate dianion uses one -SO(3) unit to O,O'-chelate to an Sr(II) cation and its third O atom to bind to another Sr(II) cation. The other -SO(3) unit binds to yet another Sr(II) atom. The four coordinated water mol-ecules are monodentate but one is disordered over two positions in a 1:1 ratio. The ?(3)-bonding mode of the dianion generates a polymeric three-dimensional network; the network is consolidated by O-H?O hydrogen bonds. The Sr(II) cation exists in an undefined eight-coordinate environment.

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.

Poly[tetra-aqua-μ(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 π-π stacking inter-actions [3.4604 (19) Å] connect the various components to form a supra-molecular structure.

Project description:In the title compound, {[Sr(C(12)H(10)O(12))(H(2)O)]·H(2)O}(n), the Sr(II) ion is coordinated by six O atoms of five symmetry-related 3,4,5,6-tetra-carb-oxy-cyclo-hexane-1,2-dicarboxyl-ate ligands and one water mol-ecule in a slightly distorted monocapped trigonal-prismatic environment. The ligands bridge the Sr(II) ions, forming a two-dimensional structure. In the crystal, O-H?O hydrogen bonds further connect the structure into a three-dimensional network.
