4-[Bis(3-phenyl-1H-pyrazol-1-yl)meth-yl]benzene-1,2-diol.

ABSTRACT: The title compound, C(25)H(20)N(4)O(2), is a ditopic ortho-hydro-quinone-based bis-(pyrazol-1-yl)methane ligand. The dihedral angles between the planes of the pyrazole rings and their attached phenyl rings are 17.4?(3) and 5.9?(4)°. The pyrazole rings make a dihedral angle of 87.84?(16)°. One of the two hy-droxy groups forms an intra-molecular hydrogen bond to the other hy-droxy group, whereas the second is involved in an inter-molecular O-H?N hydrogen bond. As a result of these inter-molecular hydrogen bonds, helical chains running along the b axis are formed.

1,2-Bis[(3,5-diphenyl-1H-pyrazol-1-yl)meth-yl]benzene.

Project description:The title compound, C(38)H(30)N(4), a potentially mono- and bidentate ligand, does not seem to form palladium complexes similar to other poly(pyrazol-1-ylmeth-yl)benzenes due to the large steric size of the phenyl substituents on the pyrazole rings. The pyrazole rings have a 21.09?(5)° angle between their mean planes and exhibit a trans-like geometry in which the in-plane lone pairs of electrons on the 2-N nitrogen atoms point in opposite directions.

{1,2-Bis[(3,5-dimethyl-1H-pyrazol-1-yl-?N)meth-yl]benzene}-dichloridozinc(II).

Project description:The title zinc complex, [ZnCl(2)(C(18)H(22)N(4))], contains a bidentate 1,2-bis(3,5-dimethyl-1H-pyrazol-1-ylmeth-yl)benz-ene ligand that binds to the zinc atom, forming a nine-membered metallocyclic ring. The geometry about the Zn atom is distorted tetra-hedral, with the largest deviation observed in the magnitude of the Cl-Zn-Cl angle. Similar distortions are observed in the cobalt analogue and related zinc compounds containing metallocyclic rings with more than six members. The copper analogue exhibits a more severe distortion of the metal coordination sphere than is observed in the title compound.

1,4-Bis[(1H-pyrazol-1-yl)meth-yl]benzene dihydrate.

Project description:The asymmetric unit of the title compound, C(14)H(14)N(4)·2H(2)O consists of two half-mol-ecules of the main mol-ecule, each situated on an inversion center, and two mol-ecules of water. One-dimensional chains of water mol-ecules are built up by O-H⋯O hydrogen bonds which are then linked with the main mol-ecule via O-H⋯N hydrogen bonds, forming a two-dimensional supra-molecular network in the ac plane.

Project description:The title compound, [Li2(C25H23BN4OP)2], features a centrosymmetric dimeric complex. The four-memberered Li2O2 ring is exactly planar due to symmetry.

The crystal structure is stabilized by two inter-molecular N-H?N hydrogen-bonds, which build a two-dimensional network developing parallel to (100). An intra-molecular N-H?N hydrogen bond also occurs.

The ethyl group is disordered over two orientations, with occupancies of 0.587?(11) and 0.413?(11).
