Crystal structure of poly[bis-(?-2-amino-4,5-di-cyano-imidazolato-?(2) N (1):N (3))-trans-bis-(N,N'-di-methyl-formamide-?O)cadmium].

ABSTRACT: In the title structure, [Cd(C5H2N5)2(C3H7NO)2] n or [Cd(adci)2(DMF)2] n , the Cd(2+) ion is located on a twofold rotation axis and is six-coordinated in a CdN4O2 manner by four imidazole N atoms of four symmetry-related 2-amino-4,5-di-cyano-imidazolate (adci) anions in the equatorial plane and by two O atoms of symmetry-related N,N-di-methyl-formamide (DMF) ligands in axial positions. The adci(-) anions bridge adjacent Cd(2+) ions [shortest Cd?Cd separation = 6.733?(3)?Å] into a layered coordination polymer extending parallel to (001). The primary amino group and the non-coordinating cyano groups of adci(-) anions are involved in hydrogen-bonding inter-actions with DMF ligands to stabilize the crystal structure.

Project description:In the title compound, [Cd(2)Cr(2)O(8)(C(12)H(8)N(2))(4)]·2H(2)O, which was obtained by hydro-thermal reaction of CdCO(3) and phenanthroline with K(2)CrO(4) at 393 K, two distorted Cd(N(4)O(2)) octa-hedra are linked through μ(2)-bridging chromate anions, forming a centrosymmetric tetra-nuclear eight-membered ring complex. The water mol-ecules link the chromate O atoms via inter-molecular O-H⋯O hydrogen bonds. These aggregates pack to a three-dimensional network through weak inter-molecular C-H⋯O and C-H⋯π hydrogen-bonding contacts.

Project description:In the title coordination polymer, {[Cd(2)(C(10)H(9)O(5))(2)(C(10)H(8)N(2))(2)(C(3)H(7)NO)(2)(H(2)O)(2)](NO(3))(2)}(n), the 3-(4-carb-oxy-phen-oxy)propionate monoanion O,O'-chelates to a Cd(II) cation through the aliphatic carboxyl-ate end. One of these O atoms is also connected to the metal cation from an inversion-related metal atom. The five O atoms bonded to the metal centre form a penta-gon, above and below which are located the N atoms of the 4,4'-bipyridine mol-ecules. The polycationic ribbon propagates along the b axis of the unit cell. The (aromatic) carboxyl end of the monoanion connects adjacent ribbons into a layer motif in the (102) plane. The nitrate ions are hydrogen bonded to the layer. The geometry of the Cd(II) atom is a trans-N(2)O(5)Cd penta-gonal bipyramid.

Crystal structure of di-μ-chlorido-bis-[di-chlorido(l-histidinium-κ<i>O</i>)cadmium(II)].

Project description:In the title compound, [Cd2(C6H9N3O2)2Cl6], the coordination polyhedra around the CdII cations are distorted trigonal bipyramids. Two of the chloride ions (one axial and one equatorial) are bridging to the other metal atom, leading to a Cd⋯Cd separation of 3.9162 (4) Å. The O atom of the l-histidinium cation lies in an axial site. In the crystal, numerous N-H⋯Cl, N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional network. Theoretical calculations and spectroscopic data are available as supporting information.

Di-μ-benzoato-κO,O':O';κO:O,O'-bis[aqua-bis-(benzoato-κO,O')(dimethylformamide-κO)europium(III)].

Project description:The title dimeric complex, [Eu(2)(C(7)H(5)O(2))(6)(C(3)H(7)NO)(2)(H(2)O)(2)], is centrosymmetric, implying that pairs of equivalent Eu(3+) ions and ligands lie trans to each other and that the two Eu(3+) ions have exactly the same coordination environment. Each Eu(3+) ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylformamide and one water molecule. The coordination polyhedron of each Eu(3+) ion can be described with a distorted monocapped square-anti-prismatic geometry. The mol-ecular structure is stabilized by intra- and inter-molecular hydrogen bonds between the water mol-ecules and benzoate O atoms.

Crystal structure of bis-(1,3-di-amino-propane-κ(2) N,N')bis-[2-(4-nitro-phen-yl)acetato-κO]cadmium.

Project description:In the structure of the title compound, [Cd(C8H6NO4)2(C3H10N2)2], the Cd(II) atom is located on a center of symmetry with one independent Cd-O distance of 2.3547 (17) Å and two Cd-N distances of 2.3265 (18) and 2.3449 (19) Å. The Cd(II) atom has an overall octa-hedral coordination environment. Several types of hydrogen-bonding inter-actions are evident. Both intra- and inter-molecular inter-actions occur between the amino groups and the O atoms of the acetate group. These N-H⋯O hydrogen bonds lead to a layered structure extending parallel to the bc plane. In addition, weak inter-molecular C-H⋯O inter-actions involving the nitro groups exist, leading to the formation of a three-dimensional network structure.

Di-μ-nicotinato-κN:O;κO:N-bis-[aqua-(ethyl-enediamine-κN,N')(nicotinato-κN)cadmium(II)] dihydrate.

Project description:The dinuclear mol-ecule of the title compound, [Cd(2)(C(6)H(4)NO(2))(4)(C(2)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, lies on an inversion centre and forms 12-membered (CdNC(3)O)(2) metallacycles with the two Cd(2+) ions bridged by two nicotinate ligands. Both Cd(2+) ions display coordination polyhedra with a distorted octa-hedral geometry that includes two pyridine N atoms from bridging and terminal nicotinate anions, two amine N atoms from chelating ethylene-diamine ligands, carboxylate O atoms from bridging nicotinate anions and water O atoms. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds result in the formation of a three-dimensional network, and π-π stacking inter-actions are observed between symmetry-related pyridine rings of bridging as well as terminal nicotinate anions (the centroid-centroid distances are 3.59 and 3.69 Å, respectively, and the distances between parallel planes of the stacked pyridine rings are 3.53 and 3.43 Å, respectively). The two methylene groups of the ethylene-diamine ligand are disordered over two positions; the site occupancy factors are ca 0.8 and 0.2.

Hexa-kis-(dimethyl-formamide-κO)manganese(II) μ-oxido-bis-[trichlorido-ferrate(III)].

Project description:The title compound, [Mn(C(3)H(7)NO)(6)][Fe(2)Cl(6)O], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes with Schiff base ligands using manganese powder and FeCl(3)·6H(2)O as starting materials. In the [Fe(2)OCl(6)](2-) anion, the O atom and the Fe atom occupy positions with site symmetry [Formula: see text] and 3, respectively, resulting in a linear Fe-O-Fe angle and a staggered conformation. The octa-hedrally surrounded cation (site symmetry [Formula: see text]) and the [Fe(2)Cl(6)O](2-) anion are alternately stacked along [001].

The Schiff base ligand is in the trans conformation.
