A one-dimensional copper(II) phenyl-ene-diphospho-nate: catena-poly[[(1,10-phenanthroline-κN,N')copper(II)]-μ(3)-[m-phenyl-enediphospho-nato-κO:O':O'']].

Project description:The title compound, [Cu(1,3-HO(3)PC(6)H(4)PO(3)H)(C(12)H(8)N(2))](n), is a coordination polymer of the metal-diphospho-nate family. The chain structure is constructed from '4+1' square-py-rami-dally coordinated copper(II) atoms bonded to chelating phenanthroline (phen) ligands and linked through 1,3-phenyldihydrogendiphospho-nate ligands. The basal plane of the Cu(II) site is defined by the phen nitro-gen donors and phospho-nate oxygen atoms from two diphospho-nate ligands, while the apical position is occupied by an oxygen donor from a third diphospho-nate ligand. The chains propagate along the a-axis direction. Inversion-related phen groups engage in π-π stacking with a mean distance of 3.376 (2) Å between the ring planes. O-H⋯O hydrogen-bonding inter-actions between the protonated {P-OH} groups of one chain and the {P=O} groups of adjacent chains stabilize the crystal packing.

Poly[bis-[μ(2)-(dimethyl-aza-nium-yl)methyl-enediphospho-nato]magnesium].

Project description:The title compound, [Mg(C(3)H(10)NO(6)P(2))(2)](n), synthesized by a hydro-thermal method, adopts a one-dimensional polymeric chain structure and is isotypic with the previously reported Cd complex based on the ligand N,N-dimethyl-amino-methane-1,1-diphospho-nic acid (H(4)L). The asymmetric unit contains one half Mg(2+) ion and one H(3)L(-) anion. The unique Mg(2+) ion lies on an inversion center and is octa-hedrally coordinated by O atoms from six phospho-nate groups of four different H(3)L(-) anions. Each H(3)L(-) anion, with one protonated N atom and two phospho-nate OH groups, serves as a tridentate ligand. Two of its six phospho-nate O atoms chelate to a Mg(2+) cation in a bidentate fashion, while a third O atom bridges to a neighbouring Mg(2+) ion. The inter-connection of Mg(2+) ions by the H(3)L(-)anions leads to the formation of a polymer chain along the a axis in which the adjacent Mg(2+) ions are doubly bridged by two equivalent H(3)L(-) anions. These discrete chains are further assembled into a three-dimensional supra-molecular network via O-H⋯O and N-H⋯O hydrogen bonds involving the non-coordin-ated phospho-nate O atoms and the protonated N atoms.

Diammonium diaqua-bis(methyl-enediphospho-nato-?O,O')cobaltate(II).

Project description:In the salt, (NH(4))(2)[Co(CH(4)O(6)P(2))(2)(H(2)O)(2)], the methyl-ene-diphospho-nate acts as a bidentate ligand and the Co(II) ion (site symmetry ) assumes an octa-hedral CoO(6) coordination geometry. The acid H atom of the ligand is distributed over two O atoms. In the crystal, a three-dimensional network is formed through O-H?O and N-H?O hydrogen bonds between the cations and anions.

Project description:The title compound, {[Ca(1.5)(C(3)H(5)Cl(2)O(6)P(2))(H(2)O)(2)]·0.5CH(3)COCH(3)·4.5H(2)O}(n), has a two-dimensional polymeric structure. The asymmetric unit contains two crystallographically independent Ca(2+) cations connected by a chelating and bridging ethyl (dichloro-methyl-ene)diphos-pho-n-ate(3(-)) ligand and an aqua ligand. One of the Ca atoms, lying on a centre of symmetry, has a slightly distorted octa-hedral geometry, while the other Ca atom is seven-coordinated in a distorted monocapped trigonal-prismatic geometry. The polymeric layers are further connected by extensive O-H?O hydrogen bonding into a three-dimensional supra-molecular network. The acetone solvent mol-ecule and one uncoordin-ated water mol-ecule are located on twofold rotation axes.

μ-Aqua-κO:O-di-μ-4-methyl-benzoato-κO:O'-bis-[(4-methyl-benzoato-κO)(1,10-phenanthroline-κN,N')nickel(II)].

Project description:In the title dinuclear complex, [Ni(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], each Ni(II) atom is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands, and one μ(2)-bridging aqua ligand. The dimeric complex is located on a crystallographic twofold axis and each Ni atom displays a distorted octa-hedral coordination geometry. The crystal structure is stabilized via intra-molecular hydrogen bonding of the bridging water mol-ecule and the uncoordinated carboxyl-ate O atoms, and by C-H⋯O and π-π stacking inter-actions [centroid-centroid distances between neighbouring phenanthroline ring systems and between the benzene ring of a 4-methyl-benzoate unit and a phenanthroline ring system are 3.662 (2) and 3.611 (3) Å, respectively].

Project description:The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicotinamide (DENA) ligands. Symmetry-related Mn(II) ions are bridged by the N and O atoms of symmetry-related DENA ligands, forming polymeric chains parallel to [100]. The coord-ination environmnts for the Mn(II) ions are slightly distorted octa-hedral. Intra-molecular O-H⋯O hydrogen bonds link bridging water mol-ecules to the carboxyl-ate O atoms of a neigh-boring polymeric chain. In the crystal structure, π-π contacts between benzene rings [centroid-centroid distance = 3.562 (1) Å] and weak C-H⋯π inter-actions are also observed.

Tetra-μ-2-methyl-benzoato-κO:O'-bis-[(ethanol-κO)copper(II)].

Project description:In the title dinuclear complex, [Cu(2)(C(8)H(7)O(2))(4)(C(2)H(5)OH)(2)], four 2-methyl-benzoato anions form a cage around two Cu(II) ions in a syn-anti configuration. Two ethanol mol-ecules coordinate the Cu atoms in apical positions, giving an overall square-pyramidal coordination geometry. The Cu⋯Cu separation is 2.600 (1) Å. In the crystal, mol-ecules are assembled into chains extending in [001] through O-H⋯O hydrogen bonds.
