Bis[4-(1-imino-eth-yl)-3-methyl-1-phenyl-1H-pyrazol-5-olato-?O,N]copper(II).

ABSTRACT: In the title complex, [Cu(C(12)H(12)N(3)O)(2)], the Cu(II) ion is tetra-coordinated by two N atoms and two O atoms from two bis-chelating 4-(1-imino-eth-yl)-3-methyl-1-phenyl-1H-pyrazol-5-olate ligands in a square-planar geometry. The two N atoms and two O atoms around the Cu(II) atom are trans to each other, as the Cu(II) atom lies on an inversion centre. The six-membered ring composed of the Cu, an O, an N and three C atoms of the ligand and the pyrazole ring is nearly planar, the largest deviation being 0.037?(4)?Å for an N atom. In the crystal, weak inter-molecular C-H?N hydrogen-bonding inter-actions link the mol-ecules into chains along the c 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).

Crystal structure of bis-{1-phenyl-3-methyl-4-[(quinolin-3-yl)imino-methyl-?N]-1H-pyrazol-5-olato-?O}zinc methanol 2.5-solvate from synchrotron X-ray diffraction.

Project description:The title compound, [Zn(C20H15N4O)2]·2.5CH3OH, I, was synthesized via the reaction of zinc acetate with the respective ligand and isolated as a methanol solvate, i.e., as I·2.5CH3OH. The crystal structure is triclinic (space group P-1), with two complex mol-ecules ( A and B ) and five methanol solvent mol-ecules in the asymmetric unit. One of the five methanol solvent mol-ecules is disordered over two sets of sites, with an occupancy ratio of 0.75:0.25. Mol-ecules A and B are conformers and distinguished by the conformations of the bidentate 1-phenyl-3-methyl-4-[(quinolin-3-yl)imino-meth-yl]-1H-pyrazol-5-olate ligands. In both mol-ecules, the zinc cations have distorted tetra-hedral coordination spheres, binding the monoanionic ligands through the pyrazolo-late O and imine N atoms. The two ligands adopt slightly different conformations in terms of the orientation of the terminal phenyl and quinoline substituents with respect to the central pyrazolo-late moiety. The mol-ecular geometries of A and B are supported by intra-molecular C-H?O and C-H?N hydrogen bonds. In the crystal of I, mol-ecules form dimers both by secondary inter-molecular Zn?O [3.140?(2)-3.553?(3)?Å] and ?-? stacking inter-actions. The dimers are linked by inter-molecular hydrogen bonds through the solvent methanol mol-ecules into a three-dimensional network.

4-[(Ethoxy-imino)(phen-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:In the mol-ecule of the title compound, C(19)H(19)N(3)O(2), the central pyrazole ring makes dihedral angles of 9.89?(3) and 66.06?(5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05?(5)°. An intra-molecular C-H?O hydrogen bond forms a six-membered ring, producing an S(6) ring motif. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link each mol-ecule to two others, forming an infinite one-dimensional supra-molecular structure along the c axis.

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.

1,3-Bis[(-)-(S)-(1-phenyl-eth-yl)imino-meth-yl]benzene.

Project description:The title compound, C(24)H(24)N(2), is an enanti-omerically pure bis-aldimine, which displays twofold crystallographic symmetry, with two C atoms of the central benzene ring lying on the symmetry axis. The imine group is slightly twisted from the benzene core, with a dihedral angle of 12.72 (16)° between the benzene ring and the C=N-C(*) plane. The terminal phenyl rings make an angle of 66.44 (4)° and are oriented in opposite directions with respect to the benzene ring. In the crystal, mol-ecules inter-act weakly through a C-H⋯π inter-action involving the phenyl rings, and form chains along the 2(1) screw-axis in the [100] direction.

Project description: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.
