ABSTRACT: The title complex, [Ni(C(12)H(11)N(2)O(2))(2)(C(3)H(7)NO)(2)], lies on on an inversion center. The Ni(II) ion is coordinated in a slightly distorted octa-hedral coordination enviroment by four O atoms from two bis-chelating 4-acety-3-methyl-1-phenyl-1H-pyrazol-5-olate ligands in the equatorial plane and two O atoms from two N,N-dimethyl-formamide ligands in the axial sites. In the crystal structure, weak inter-molecular ?-? stacking inter-actions with centroid-centroid distances of 3.7467?(13)?Å link mol-ecules into chains extending alongthe b axis.

Bis[4-(4-chloro-benzo-yl)-3-methyl-1-phenyl-1H-pyrazol-5-olato-κO,O']bis-(methanol-κO)nickel(II).

Project description:The mol-ecular structure of the neutral mononuclear title complex, [Ni(C(17)H(12)ClN(2)O(2))(2)(CH(3)OH)(2)], is centrosymmetric. The Ni(II) atom, which is located on an inversion center, is in a distorted octahedral coordination, defined by four O atoms from two ligands as well as two O atoms from two methanol mol-ecules. Inter-molecular O-H⋯N hydrogen bonds between the hy-droxy group of methanol and a pyrazole N atom link the mol-ecules, forming a two-dimensional network parallel to (100).

Bis(4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5-olato-?(2)O,O')bis-(ethanol-?O)cobalt(II).

Project description:The title compound, [Co(C(17)H(13)N(2)O(2))(2)(C(2)H(5)OH)(2)], is a Co(II) complex with two 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5-olate (BMPP) ligands and two coordinating ethanol mol-ecules. In the asymmetric unit, there are two half mol-ecules, with the Co(II) atoms located on inversion centres. The two cobalt complexes have slightly different geometries and in one, the ethyl group of the ethanol is disordered over two sets of sites [occupancy ratio 0.757?(7):0.243?(7)]. Each BMPP ligand is deprotonated with the negative charge delocalized. The hy-droxy group of each ethanol mol-ecule forms hydrogen bonds with a pyrazole N atom in an adjacent BMPP ligand. Weaker C-H?O and C-H?N inter-actions link the mol-ecules into a three-dimensional structure.

In the crystal, weak inter-molecular C-H?N hydrogen-bonding inter-actions link the mol-ecules into chains along the c axis.

Project description:The title Schiff base compound, C(23)H(23)N(5)O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl-pyrazole-4-carbaxaldehyde. The mol-ecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H?O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72?(10)° and the dihedral angles between the pyrazole rings and the adjacent phenyl rings are 58.67?(10) and 46.58?(11)°. The crystal structure is stabilized by weak C-H?? inter-actions involving the pyrazolone and phenyl rings.

Project description:The title compound, [Ni(C7H6N2O3)(C12H8N2)2]·3.5H2O, crystallizes as a neutral mononuclear complex with 3.5 solvent water mol-ecules.

In the crystal, O-H?O, N-H?O and O-H?N hydrogen bonds involving the solvent water mol-ecules and pyrazole-5-carboxyl-ate ligands form layers parallel to the ab plane. These layers are linked further via weak ?-? inter-actions between two adjacent phenanthroline mol-ecules, with centroid-to-centroid distances in the range 3.886?(2)-4.018?(1)?Å, together with C-H?? contacts, forming a three-dimensional network.
