Tris(ethyl-enediamine)-nickel(II) 1H-pyrazole-3,5-dicarboxyl-ate 1.67-hydrate.

ABSTRACT: The asymmetric unit of the title compound, [Ni(C(2)H(8)N(2))(3)](C(5)H(2)N(2)O(4))·1.67H(2)O, consists of three [Ni(en)(3)](2+) dications (en is ethyl-enediamine), three [(pzdc)(3)](2-) dianions (pzdc is pyrazole-3,5-dicarboxyl-ate) and five water mol-ecules. In each complex dication, the Ni(II) atom is coordinated by six N atoms from three en ligands forming a distorted octa-hedral coordination geometry. In the crystal, the ions and water mol-ecules are linked into a three-dimensional framework by a large number of N-H?O and O-H?O hydrogen bonds.

Dimethyl 1-cyano-methyl-1H-pyrazole-3,5-dicarboxyl-ate.

Project description:The title mol-ecule, C(9)H(9)N(3)O(4), syhthesized from 1H-pyrazole-3,5-dicarboxylic acid and 2-bromo-acetonitrile, is approximately planar; the inter-planar angles between the pyrazole ring and the mean planes of the two carboxylate units and the cyanomethyl unit are 4.49?(10), 5.56?(9) and 5.03?(19)°, respectively. In the crystal, inversion dimers linked by pairs of weak C-H ?O bonds occur, and the packing is further stabilized by aromatic ?-? stacking [centroid-centroid separation = 3.793?(4)?Å].

2-Amino-5-methyl-pyridinium 1H-pyrazole-3,5-dicarboxyl-ate trihydrate.

Project description:In the title compound, 2C(6)H(9)N(2) (+)·C(5)H(2)N(2)O(4) (2-)·3H(2)O, the 1H-pyrazole-3,5-dicarboxyl-ate anion is close to planar [maximum deviation = 0.208 (1) Å]. The two distinct 2-amino-5-methyl-pyridinium cations are also almost planar, with maximum deviations of 0.018 (2) and 0.014 (2) Å. In the crystal, pairs of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect neighbouring mol-ecules into dimers, generating R(2) (2)(8) and R(2) (4)(8) ring motifs, respectively. Further inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Dimethyl 1-(4-cyano-benz-yl)-1H-pyrazole-3,5-dicarboxyl-ate.

Project description:The title compound, C(15)H(13)N(3)O(4), was synthesized from dimethyl 1H-pyrazole-3,5-dicarboxyl-ate and 4-(bromo-meth-yl)benzonitrile. The inter-planar angle between the pyrazole and cyano-benzyl ring planes is 71.74 (17)° and an intramolecular C-H⋯O interaction occurs. The crystal structure is stabilized by π-π stacking inter-actions between the neighbouring pyrazole and benzene rings [centroid-centroid distances of 3.5074 (16) and 3.9401 (15) Å, respectively]. One of the methyl groups is disordered over two positions of equal occupancy.

Hexakis(1H-imidazole-?N)nickel(II) triaqua-tris(1H-imidazole-?N)nickel(II) bis-(naphthalene-1,4-dicarboxyl-ate).

Project description:The crystal structure of the title compound, [Ni(C(3)H(4)N(2))(6)][Ni(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), contains uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Ni(II) complex cations, both assuming distorted octa-hedral geometries. One Ni(II) ion is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Ni(II) ion is located on a twofold rotation axis and is coordinated by three water mol-ecules and three imidazole mol-ecules in a mer-NiN(3)O(3) arrangement. The naphthalene-dicarboxyl-ate dianion links both Ni(II) complex cations via O-H?O and N-H?O hydrogen bonding, but no ?-? stacking is observed between aromatic rings in the crystal structure. One imidazole ligand is equally disordered over two sites about a twofold rotation axis; one N atom and one water O atom have site symmetry 2.

Project description:The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O.
