Dimethyl 1-(3-cyanobenzyl)-1H-pyrazole-3,5-dicarboxylate
In the mol-ecule of the title compound, C(15)H(13)N(3)O(4), the dihedral angle between the pyrazole and benzene ring planes is 67.7 (1)°. The crystal structure is stabilized by an intra-molecular C-H⋯O hydrogen bond and two weak inter-molecular C-H⋯O inter-actions.
متن کاملDimethyl 1-cyanomethyl-1H-pyrazole-3,5-dicarboxylate
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, a...

In the title pyrazole derivative, C(11)H(11)N(3)O(2), the benzene ring is twisted [dihedral angle = 31.38 (12)°] with respect to the pyrazole ring (r.m.s. deviation = 0.009 Å). The nitro group is effectively coplanar with the benzene ring to which it is attached [O-N-C-C torsion angle = -6.5 (3)°]. Supra-molecular chains along the b axis are formed owing to π-π inter-actions [3.8653 (2) Å] betw...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(14)N(2)O(2), in which the dihedral angles between the substituted phenyl ring and the pyrazole ring are 86.5 (2) and 82.3 (3)°. The crystal packing features weak inter-molecular C-H⋯O inter-actions.
متن کاملDichlorido(3,5-dimethyl-1H-pyrazole)[(3,5-dimethyl-1H-pyrazol-1-yl)(o-tolyl)methanone]palladium(II)
In the title compound, [PdCl(2)(C(5)H(8)N(2))(C(12)H(12)N(2)O)], the Pd atom adopts a slightly distorted trans-PdCl(2)N(2) square-planar arrangement. The different Pd-N bond lengths can be related to the the electron-withdrawing effect of the o-toluoyl group on the substituted pyrazole ligand. The complex crystallizes as centrosymmetric hydrogen-bonded dimers through N-H⋯Cl linkages.
