Bis(2-amino-pyrimidine-κN)diaqua-dinitrato-κO;κO,O'-cadmium(II) monohydrate.

ABSTRACT: In the title compound, [Cd(NO(3))(2)(C(4)H(5)N(3))(2)(H(2)O)(2)]·H(2)O, the Cd atom is seven-coordinated by two 2-amino-pyrimidine mol-ecules, two water mol-ecules, one bidentate nitrate anion and one monodentate nitrate anion. A network of N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds helps to consolidate the crystal structure.

Diaqua-bis(2-chloro-benzoato-κO)bis-(nicotinamide-κN)nickel(II).

Project description:The title Ni(II) complex, [Ni(C(7)H(4)ClO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Ni atom located on an inversion centre. The mol-ecule contains two 2-chloro-benzoate (CB) and two nicotinamide (NA) ligands and two water mol-ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 29.48 (16)°, while the pyridine and benzene rings are oriented at a dihedral angle of 83.16 (5)°. In the crystal structure, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into infinite chains. π-π Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.952 (1) Å] may further stabilize the crystal structure. There is also a C-H⋯π inter-action.

Aquabis(benzoato-κO)bis-(1H-imidazole-κN)copper(II) monohydrate.

Project description:In the title compound, [Cu(C(7)H(5)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)]·H(2)O, the Cu(II) atom is in a distorted square-pyramidal environment. The mol-ecules are assembled into double chains extending along [010] by N-H⋯O hydrogen bonds. These double chains are linked by O-H⋯O hydrogen bonds, forming layers parallel to (02); the layers are linked into a three-dimensional network by van der Waals inter-actions.

catena-Poly[[diaqua-bis-(isoquinoline-κN)cobalt(II)]-μ-succinato-κO:O].

Project description:In the title compound, [Co(C(4)H(4)O(4))(C(9)H(7)N)(2)(H(2)O)(2)](n), the Co(II) cation, located on an inversion center, is coordinated by two succinate anions, two isoquinoline ligands and two water mol-ecules in a distorted octa-hedral geometry. The succinate anion, located across another inversion center, bridges the Co cations, forming polymeric chains running along the b axis. The partially overlapped arrangement of parallel isoquinoline ring systems of adjacent polymeric chains and the shorter face-to-face distance of 3.402 (6) Å indicates the existence of weak π-π stacking in the crystal structure. Classical intra- and inter-molecular O-H⋯O hydrogen bonding and weak non-classical inter-molecular C-H⋯O hydrogen bonding help to stabilize the crystal structure.

Project description:In the crystal structure of the title Co(II) complex, [Co(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the metal centre is located on an inversion center and is coordinated by two 4-formyl-benzoate (FOB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules in a slightly distorted CoO(4)N(2) octa-hedral geometry. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into infinite chains. π-π contacts between the parallel pyridine rings of neighboring DENA ligands [centroid-centroid distance = 3.652 (3) Å] further stabilize the crystal structure.

Diaqua-bis(pyrimidine-2-carboxylic acid-κN,O)cobalt(II) dichloride.

Project description:In the title salt, [Co(C(5)H(4)N(2)O(2))(2)(H(2)O)(2)]Cl(2), the Co(II) ion is located on an inversion center. It is chelated by two neutral pyrimidine-2-carboxylic acid molecules and is coordinated by two water mol-ecules in an octa-hedral coordination geometry. The cations and anions are linked via O-H⋯Cl hydrogen bonds into a layer structure; an intra-molecular O-H⋯N hydrogen bond connects the carboxylic acid group to the pyrimidine N atom.

μ-2,3,5,6-Tetra-2-pyridylpyrazine-κN,N,N:κN,N,N-bis-[(methanol-κO)(nitrato-κO,O')(nitrato-κO)cadmium(II)].

Project description:The title complex, [Cd(2)(NO(3))(4)(C(24)H(16)N(6))(CH(4)O)(2)], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each Cd(II) center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) Å from that plane. The two Cd(II) ions are above and below the plane of the pyrazine ring of the tppz ligand, oriented with respect to the pyridine rings at dihedral angles of 38.01 (3) and 31.90 (3)°. The dihedral angle between the two pyridine rings is 41.11 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules.

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 compound, [Cd(NO3)2(C13H11N3)2], the CdII atom lies on a twofold rotation axis and is coordinated by four N atoms and two O atoms, provided by two bidentate 2-(1H-benzimidazol-2-yl)aniline ligands, and two nitrato O atoms, forming a distorted octa-hedral geometry [range of bond angles around the Cd atom = 73.82 (2)-106.95 (8)°]. In the ligand, the dihedral angle between the aniline ring and the benzimidazole ring system is 30.43 (7)°. The discrete complex mol-ecule is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
