ABSTRACT: In the title compound, C(20)H(17)ClN(2)O(3), the dihedral angles between the pyrazole ring and the substituted and unsubstituted benzene rings are 3.64?(13) and 81.15?(17)°, respectively. Mol-ecules are connected via three pairs of weak hydrogen bonds into a centrosymmetric dimer. The crystal structure is stabilized by inter-molecular C-H?O and C-H?? inter-actions.

Project description:The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007?Å) and the N- and C-bound phenyl rings are 48.10?(7) and 72.01?(7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO(2) group is also twisted out of this plane, with an O-C-C-N torsion angle of -29.04?(11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonyl-phenyl ring to the other. The dihedral angle between the two ring planes is 70.63?(7) °. Supra-molecular arrays are formed in the crystal structure sustained by C-H?O and C-H??(pyrazole) inter-actions and methyl-C-H??(N-bound benzene) contacts.

Ethyl 5-amino-1-(6-chloro-pyridazin-3-yl)-1H-pyrazole-4-carboxyl-ate.

Project description:In the title compound, C(10)H(10)ClN(5)O(2), the dihedral angle between the aromatic rings is 0.16?(9)°. Two S(6) ring motifs are formed due to intra-molecular N-H?N and N-H?O hydrogen bonds. In the crystal, inversion dimers linked by pairs of N-H?N hydrogen bonds generate R(2) (2)(14) [or R(4) (4)(10) via the intra-molecular hydrogen bonds] ring motifs. Polymeric chains propagating in [210] are formed as a result of inter-linking the dimers by pairs of C-H?N inter-actions, completing R(2) (2)(6) ring motifs.

Ethyl 1-(2-hy-droxy-eth-yl)-2-phenyl-1H-benzimidazole-5-carboxyl-ate.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(18)H(18)N(2)O(3).

Ethyl 5-amino-1-(4-chloro-2-nitro-phen-yl)-1H-pyrazole-4-carboxyl-ate.

Project description:In the mol-ecule of the title compound, C(12)H(11)ClN(4)O(4), the pyrazole ring is coplanar with the amino and ethoxy-carbonyl groups within 0.026?(2) and 0.105?(2)?Å, respectively. The C(6) ring of the 4-chloro-2-nitro-phenyl group is twisted by 53.58?(4)° relative to the plane of the pyrazole ring. The planar structure of the pyrazole ring is stabilized by an intra-molecular N-H?O hydrogen bond between its substituents. Neighbouring mol-ecules are linked through inter-molecular N-H?N and N-H?O hydrogen bonds, giving rise to one-dimensional tapes along the b axis. Mol-ecules in the chain are linked to those of an adjacent chain through weak C-H?O inter-actions, forming a three-dimensional network.
