Poly[[tetra-aqua-tetra-kis-[μ(3)-5-(pyridine-4-carboxamido)-isophthalato]cobalt(II)dierbium(III)] tetra-hydrate].

ABSTRACT: In the centrosymmetric polymeric title compound, {[CoEr(2)(C(14)H(8)N(2)O(5))(4)(H(2)O)(4)]·4H(2)O}(n), the Er(III) cation has a coordination number of eight and is surrounded by seven carboxyl-ate O atoms from four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands and one water mol-ecule, forming a distorted square-anti-prismatic arrangement. The Co(II) cation is located on an inversion center and is coordinated by two pyridine N atoms, two carboxyl-ate O atoms and two water mol-ecules in a distorted octa-hedral geometry. The asymmetric unit contains two anionic L ligands. One bridges two Er(III) cations and one Co(II) cation through two carboxyl-ate groups and one pyridine N atom, while the other bridges two Er(III) cations and one Co(II) cation through two carboxyl-ate groups. Extensive O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bonding inter-actions are present in the crystal, involving all uncoordinated water mol-ecules and the uncoordinated pyridine N atom of one of the ligands bonded to an adjacent coordinated water mol-ecule. The title compound is isotypic with the gadolinium analogue.

catena-Poly[[[diaqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato-[tetra-aqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

Bis(5-hy-droxy-isophthalato-κO (1))bis-[4-(pyridine-3-carboxamido-κN (3))pyridinium]copper(II) tetra-hydrate.

Project description:In the title compound, [Cu(C11H10N3O)2(C8H4O5)2]·4H2O, the Cu(II) ion, located on a crystallographic inversion center, is coordinated in a square-planar environment by two trans-O atoms belonging to two monodentate 5-hy-droxy-isophthalate (hip) dianions and two trans nicotinamide pyridyl N-donor atoms from monodentate protonated pendant N-(pyridin-4-yl)nicotinamide (4-pnaH) ligands. The protonated 4-pyridyl-amine groups engage in N-H(+)⋯O(-) hydrogen-bond donation to unligated hip O atoms to construct supra-molecular chain motifs parallel to [100]. Water mol-ecules of crystallization, situated between the chains, engage in O-H⋯O hydrogen bonding to form supra-molecular layers and the overall three-dimensional network structure.

Tetra-kis(μ(2)-2-methyl-3,5-dinitro-benzoato-κO:O)bis-[aqua-copper(II)] tetra-hydrate.

Project description:The title compound, [Cu(2)(C(8)H(5)N(2)O(6))(4)(H(2)O)(2)]·4H(2)O, forms a centrosymmetric paddle-wheel-type dimer with an intra-molecular Cu⋯Cu distance of 2.6540 (4) Å. The Cu(II) atom is in a square-pyramidal coordination environment formed by four O atoms of four carboxyl-ate groups and one water mol-ecule, which is located in the apical position. The carboxyl-ate groups are twisted relative to the benzene rings by 11.09 (16) and 45.55 (19)°. The nitro groups are not coplanar with the parent aromatic rings [dihedral angles = 16.2 (3)-51.45 (14)°]. O-H⋯O hydrogen bonds between the coordinated water mol-ecules and one of the nitro groups, as well as π-π stacking inter-actions [centroid-centroid distance = 3.5764 (12) Å] between the benzene rings, assemble the complex mol-ecules into a one-dimensional polymeric structure which is further extended into a three-dimensional polymeric network via O-H⋯O hydrogen bonds involving the water molecules of crystallization.

(μ-2,2',2'',2'''-{[Pyrazine-2,3,5,6-tetra-yltetra-kis(methyl-ene)]tetra-kis(sulfanedi-yl)}tetra-acetato)bis-[aqua-nickel(II)] hepta-hydrate.

Project description:Reaction of the ligand 2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetic acid (H4L1), with NiCl2 leads to the formation of a binuclear complex, (μ-2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetato-κ5 O,S,N 1,S',O':κ5 O'',S'',N 4,S''',O''')bis[aqua-nickel(II)] hepta-hydrate, {[Ni2(C16H16N2O8S4)(H2O)2]·7H2O} (I). It crystallizes with two half mol-ecules in the asymmetric unit. The complete mol-ecules are generated by inversion symmetry, with the center of the pyrazine rings being located at crystallographic centres of inversion. The ligand coordinates two NiII ions in a bis-penta-dentate manner and the sixfold coordination sphere of each nickel(II) atom (NiS2O3N) is completed by a water mol-ecule. The complex crystallized as a hepta-hydrate. The binuclear complexes are linked by Owater-H⋯Ocarbon-yl hydrogen bonds, forming layers parallel to the (101) plane. This layered structure is additionally stabilized by weak C-H⋯O hydrogen bonds. Further O-H⋯O hydrogen bonds involving binuclear complexes and solvent water mol-ecules, together with weak C-H⋯S hydrogen bonds, link the layers to form a supra-molecular framework.

Poly[[tetra-aqua-(μ(4)-imidazole-4,5-dicarboxyl-ato)(μ(3)-imidazole-4,5-dicarboxyl-ato)-μ(3)-sulfato-μ(2)-sulfato-cobalt(II)dierbium(III)] monohydrate].

Project description:The asymmetric unit of the title compound, {[CoEr(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(2)(H(2)O)(4)]·H(2)O}(n), contains a Co(II) ion, two Er(III) ions, two imidazole-4,5-dicarboxyl-ate (imdc) ligands, two SO(4) (2-) anions, four coordinated water mol-ecules and one uncoordinated water mol-ecule. The Co(II) ion is six-coordinated by two O atoms from two coordinated water mol-ecules and two O atoms and two N atoms from two imdc ligands in a slightly distorted octa-hedral geometry. Both Er(III) ions are eight-coordinated in a bicapped trigonal-prismatic coordination geometry. One Er(III) ion is coordinated by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and one water O atom; the other Er(III) ion is bonded to five O atoms from three imdc ligands, two O atoms from two SO(4) (2-) anions as well as one coordinated water mol-ecule. The coordinated metal units are connected by bridging imdc ligands and sulfate ions, generating a two-dimensional heterometallic layer. The two-dimensional layers are stacked along the b axis via N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions between water mol-ecules, SO(4) (2-) anions, and imdc ligands, generating a three-dimensional framework.

cyclo-Tetra-μ-malato-κO,O',O'':O'''-tetra-kis[bis-(1H-benzimidazole-κN)cobalt(II)] eicosa-hydrate.

Project description:The title compound, [Co(4)(C(4)H(4)O(5))(4)(C(7)H(6)N(2))(8)]·20H(2)O, consists of tetra-nuclear Co(II) complexes and disordered uncoordinated water mol-ecules. The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a distorted octa-hedral coordination geometry. The tridentate malate dianion chelates the Co(II) ion, and the chelate six- and five-membered rings show half-chair and envelope configurations, respectively. A face-to-face separation of 3.494 (9) Å between parallel benzimidazole ligands indicates the existence of π-π stacking between adjacent complexes. The crystal structure also involves N-H⋯O and O-H⋯O hydrogen bonds.
