Catena-Poly[[tetra-aqua-?-aqua-bis-(?(4)-pyrimidine-2-carboxyl-ato)tetra-lithium] dichloride].

ABSTRACT: The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(2)(H(2)O)(5)]Cl(2), contains two Li(I) cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetra-hedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxyl-ate O atoms are bidentate and bridge the metal ions, forming a divalent cation. Charge balance is maintained by two chloride anions. The building blocks, bridged by Li(I) cations, form cationic ribbons with chloride anions in the space between them. The ribbons propagate in [010] and are held together by a network of weak O-H?O hydrogen bonds which operate in the space between adjacent ribbons.

Bis(?(3)-pyrimidine-4-carboxyl-ato)bis-(?(2)-pyrimidine-4-carboxyl-ato)tetra-kis-(aqua-lithium).

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(4)(H(2)O)(4)], contains two symmetry-independent Li(I) ions, two symmetry-independent ligands and two symmetry-independent coordinated water mol-ecules. They form a dinuclear unit in which the two Li(I) ions are bridged by two carboxyl-ate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetra-meric mol-ecule. One of the Li(I) ions shows a distorted tetra-hedral coordination geometry, the other a distorted trigonal-bipyramidal environment. The tetra-mers are held together by hydrogen bonds in which coordinated water mol-ecules act as donors, and the carboxyl-ate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

Poly[hexa-aqua-bis-(?(4)-pyrimidine-4,6-dicarboxyl-ato)tetra-lithium].

Project description:The asymmetric unit of the title compound, [Li(4)(C(6)H(2)N(2)O(4))(2)(H(2)O)(6)](n), comprises two Li(+) ions bridged by a completely deprotonated pyrimidine-3,6-dicarboxyl-ate ligand and coordinated by two water mol-ecules; the asymmetric units related by an inversion operation create a structural unit which forms part of a two-dimensional polymeric structure parallel to (10-1). One of the Li(+) ions shows a distorted tetra-hedral arrangement involving two symmetry-related coordinating water mol-ecules and two carboxyl-ate O atoms. The other Li(+) ion is in distorted trigonal-bipyramidal geometry defined by N and O atoms of the ligands and a water mol-ecule. Water O atoms are proton donors to carboxyl-ate O atoms forming hydrogen bonds.

catena-Poly[bis-(4-amino-pyridinium) [[tetra-aqua-nickel(II)]-?-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

catena-Poly[[?(2)-aqua-diaqua-bis-(?(4)-pyridazine-3,6-dicarboxyl-ato)tetra-lithium] monohydrate].

Project description:In the polymeric structure of the title compound {[Li(2)(C(6)H(2)N(2)O(4))(2)Li(H(2)O)(2)Li(H(2)O)]·H(2)O}(n), the coordination of two independent Li(I) ions is distorted trigonal-bipyramidal and that of the other two independent Li(I) ions is distorted tetra-hedral. The former two Li(I) ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxyl-ate ligands, making a dimeric moiety. The carboxyl-ato-O atoms of both bidentate ligands bridge the dimers to adjacent independent aqua-coordinated Li(I) ions, forming mol-ecular ribbons. The latter are bridged by ligand carboxyl-ato and aqua O atoms, forming mol-ecular layers parallel to (100) which are held together by an extended system of O-H?O hydrogen bonds.

catena-Poly[[(6-carb-oxy-pyrazine-2-carboxyl-ato)lithium]-?-aqua].

Project description:The asymmetric unit of the title compound, [Li(C(6)H(3)N(2)O(4))(H(2)O)](n), contains an Li(I) ion with a distorted trigonal-bipyramidal coordination environment. It is chelated by a singly protonated ligand mol-ecule via its heterocyclic N atom, by two O aoms, each donated by an adjacent carboxyl-ate group, and is further coordinated by a water O atom which acts as a bridge, forming a mol-ecular ribbon. A proton attached to one of the carboxyl-ate O atoms is situated on an inversion centre and forms a short centrosymmetric hydrogen bond, generating mol-ecular layers parallel to the ac plane. These layers are held together by weak O-H?O hydrogen bonds in which the coordinated water mol-ecules act as donors, whereas carboxyl-ate O atoms are acceptors.

Poly[?6-(naphthalene-2,6-di-carboxyl-ato)-bis-(aqua-lithium)].

Project description:The title compound, [Li2(C12H6O4)(H2O)2] n , crystallizes with one half of the molecular entities in the asymmetric unit. The second half is gererated by inversion symmetry. The crystal structure has a layered arrangement built from distorted edge-sharing LiO3(OH)2 tetra-hedra parallel to (100), with naphthalenedi-carboxyl-ate bridging the LiO3(OH)2 layers along the [100] direction. Hydrogen bonding between the water molecule and adjacent carboxylate groups consolidates the packing.

Project description:The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H?O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.

Tetra-aqua-bis-[2-(pyridin-4-yl-?N)pyrimidine-5-carboxyl-ato]zinc.

Project description:In the title complex, [Zn(C(10)H(6)N(3)O(2))(2)(H(2)O)(4)], the Zn(II) ion lies on an inversion center and is coordinated in a slightly distorted octa-hedral geometry by two N atoms from two 2-(pyridin-4-yl)pyrimidine-5-carboxyl-ate ligands and four water mol-ecules. In the symmetry-unique part of the mol-ecule, the pyridine and pyrimidine rings form a dihedral angle of 7.0?(1)°. In the crystal, the coordinating water mol-ecules act as donor groups and carboxyl-ate O atoms act as acceptors in O-H?O hydrogen bonds, forming a three-dimensional network.

catena-Poly[[tetra-aqua-manganese(II)]-?-5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium-?O:O].

Project description:In the title coordination polymer, [Mn(C(8)H(5)NO(5))(H(2)O)(4)](n), the Mn(II) atom is coordinated by two carboxyl-ate O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium (L(2-)) ligands and by four water mol-ecules in a distorted octa-hedral geometry. The L(2-) ligands bridge the Mn atoms into an infinite chain motif along [100]; the chains are further inter-linked by O-H?O hydrogen bonds into a three-dimensional supra-molecular net.

Poly[[tetra-aqua-bis-(?(3)-5-carboxybenzene-1,2,4-tri-carboxyl-ato)tricadmium] tetra-hydrate].

Project description:There are three independent Cd(II) ions in the title complex, {[Cd(3)(C(10)H(3)O(8))(2)(H(2)O)(4)]·4H(2)O}(n), one of which is coordinated by four O atoms from three 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by two water mol-ecules in a distorted octa-hedral geometry. The second Cd(II) ion is coordinated by five O atoms from four 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by one water mol-ecule also in a distorted octa-hedral geometry while the third Cd(II) ion is coordinated by five O atoms from three 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by one water mol-ecule in a highly distorted octa-hedral geometry. The 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands bridge the Cd(II) ions, resulting in the formation of a three-dimensional structure. Intra- and inter-molecular O-H?O hydrogen bonds are present throughout the three-dimensional structure.
