Poly[diaqua-(?-oxalato)(?-2-oxido-pyridinium-3-carboxyl-ato)praseo-dymium(III)].

ABSTRACT: In the title complex, [Pr(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)(2)](n), each Pr(III) ion is coordinated by eight O atoms from two 2-oxynicotinate ligands, two oxalate ligands and two water mol-ecules, displaying a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups link adjacent praseodymium metal centres, forming layers parallel to the bc plane. The crystal packing is stabilized by inter-molecular O-H?O and N-H?O hydrogen bonds.

Project description:In the title complex, [La(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by one N and three O atoms from two pyrazine-2-carboxylate ligands, by four O atoms from two oxalate ligands and by two O atoms of two water molecules, displaying a distorted bicapped square-anti-prismatic geometry.

The layers are further connected by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network.

Project description:In the title complex, {[Dy(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)]·H(2)O}(n), the Dy(III) ion is coordinated by seven O atoms from two 2-oxidopyridinium-3-carboxylate ligands, two oxalate ligands and one water mol-ecule, displaying a distorted bicapped trigonal-prismatic geometry. The carboxyl-ate groups of the 2-oxidopyridinium-3-carboxylate and oxalate ligands link dysprosium metal centres, forming layers parallel to (100). These layers are further connected by inter-molecular O-H?O hydrogen-bonding inter-actions involving the coordin-ated water mol-ecules, forming a three-dimensional supra-molecular network. The uncoordinated water mol-ecule is involved in N-H?O and O-H?O hydrogen-bonding inter-actions within the layer.

Project description:In the title complex, {[Ho(C(2)O(4))(C(6)H(4)NO(3))(H(2)O)]·(H(2)O)}(n), the Ho(III) ion is coordinated by three O atoms from two 2-oxidopyridinium-3-carboxylate ligands, four O atoms from two oxalate ligands and one water mol-ecule in a distorted bicapped trigonal-prismatic geometry. The 2-oxidopyridin-ium-3-carboxylate and oxalate ligands link the Ho(III) ions into a layer in (100). These layers are further connected by inter-molecular O-H?O hydrogen bonds involving the coordinated water mol-ecules to assemble a three-dimensional supra-molecular network. The uncoordin-ated water mol-ecule is involved in N-H?O and O-H?O hydrogen bonds within the layer.

Poly[[tetra-aqua-di-?(4)-oxalato-?(2)-oxalato-dineo-dymium(III)] dihydrate].

Project description:The title compound, {[Nd(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), was synthesized hydro-thermally in the presence of bis-(carb-oxy-ethyl-germanium) sesquioxide. It is isostructural with the corresponding Pr compound [Yang et al. (2009). Acta Cryst. E65, m1152-m1153]. The Nd(3+) cation is nine-coordinated and its coordination polyhedron can be described as a distorted tricapped trigonal prism. Two Nd(3+) ions are connected by two O atoms from two oxalate ions to give a dinuclear Nd(2) unit. The unit is further linked to four others via four oxalate ions yielding a layerparallel to (0-11). The linkages between the layers by neighbouring oxalate anions lead to a three-dimensional framework with channels along the c axis. The coordinating and free water mol-ecules are located in the channels and make contact with each other and the host framework by weak O-H?O hydrogen bonds.

Poly[[(?-3-amino-pyrazine-2-carboxyl-ato-?N,O:O')diaqua-(?-oxalato-?O,O:O,O)lanthanum(III)] monohydrate].

Project description:The water-coordinated La(III) atom in the title compound, {[La(C(5)H(4)N(3)O(2))(C(2)O(4))(H(2)O)(2)]·H(2)O}(n), is N,O-chelated by a 3-amino-pyrazine-2-carboxyl-ate ion; this ion links adjacent metal atoms to form a chain parallel to [010]. The oxalate ion serves as a bis-bidentate chelate that links adjacent metal atoms to form a chain parallel to [001]. The two bridging ions give rise to a layer motif parallel to (100) in which the La(III) atom exists in a distorted tricapped trigonal prismatic geometry. Extensive hydrogen bonding between the constituents stabilizes the structure.

Project description:In the title compound, [Mn(2)(C(2)O(4))(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)](n), the Mn(II) atom exhibits a distorted octa-hedral coordination geometry, with the centrosymmetric oxalate anion and the monoanionic pyrimidine-2-carboxyl-ate ligands generating a two-dimensional honeycomb network with a (6,3)-topology.

Project description:The asymmetric unit of the title compound, [MnBr(2)(C(6)H(4)NO(2))(H(2)O)(2)](n), contains one monomeric unit of the neutral linear coordination polymer. The Mn(3+) ions are bridged by anionic pyridine-2-carboxyl-ate (pic) ligands, thereby forming a chain-like structure along the c axis, and are six-coordinated in a distorted octa-hedral environment by two O atoms of the two different carboxyl-ate groups, two O atoms of two water mol-ecules and two Br atoms. The complex displays inter-molecular O-H?Br, O-H?N, O-H?O, C-H?O and C-H?Br hydrogen bonding. There may also be inter-molecular ?-? inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.993?(8)?Å.

Poly[diaqua-(μ(2)-oxalato-κO,O:O,O)(μ(2)-pyrazine-2-carboxyl-ato-κN,O:O,O')neodymium(III)].

Project description:In the title complex, [Nd(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the Nd(III) atom is ten-coordinated by one N atom and three O atoms from two pyrazine-2-carboxyl-ate ligands, four O atoms from two oxalate ligands and two water mol-ecules in a distorted bicapped square-anti-prismatic geometry. The two crystallographically independent oxalate ligands, each lying on an inversion center, act as bridging ligands, linking Nd atoms into an extended zigzag chain. Neighboring chains are linked by the pyrazine-2-carboxyl-ate ligands into a two-dimensional layerlike network in the (10) plane. The layers are further connected by O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional supra-molecular network.

Project description:The asymmetric unit of the title complex, {[AgEr(C(5)H(3)N(2)O(2))(2)(C(2)O(4))]·H(2)O}(n), contains one Er(III) atom, one Ag(I) atom, two pyrazine-2-carboxyl-ate (pyc) ligands, two half oxalate ligands (each lying on an inversion center) and one uncoordinated water mol-ecule. The Er(III) atom is coordinated by two O atoms and two N atoms from two pyc ligands, one O atom from a third pyc ligand and four O atoms from two oxalate ligands in a distorted monocapped square-anti-prismatic geometry. The Ag(I) atom is coordinated by two N atoms from two pyc ligands, one O atom from a third pyc ligand and one O atom from one oxalate ligand. The crystal structure exhibits a three-dimensional heterometallic polymeric network. O-H?O hydrogen bonding between the uncoordinated water mol-ecule and carboxyl-ate O atoms is observed.
