4-Bromo-1H-pyrrole-2-carboxylic acid
In the title compound, C(5)H(4)BrNO(2), the non-H atoms of the pyrrole ring and the Br atom are approximately coplanar, with an r.m.s. deviation from the best fit plane of 0.025 (6) Å;. The dihedral angle between the plane of the carb-oxy group and this plane is 14.1 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules together, forming corrugated sheets parallel to the bc plane.

The asymmetric unit of the title compound, C(13)H(12)N(2)O(2), obtained in a search for analogs of the fungicide fludioxonil [systematic name: 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile], contains two independent mol-ecules, A and B. The benzene and pyrrole rings are inclined to each other at 38.5 (1) and 29.3 (1)° in mol-ecules A and B, respectively. In the crystal, bifurc...
متن کامل4-Acetyl-1H-pyrrole-2-carbaldehyde
The title compound, C(7)H(7)NO(2), was synthesized via a one-pot Vilsmeier-Haack and subsequent Friedel-Crafts reaction. The pyrazole ring makes dihedral angles of 4.50 (9) and 2.06 (8)°, respectively, with the aldehyde and acetyl groups. In the crystal, classical N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions assemble the mol-ecules into a chain along the b axis.
متن کاملMethyl 4-(trifluoromethyl)-1H-pyrrole-3-carboxylate
In the title compound, C7H6F3NO2, all the non-H atoms except for one of the F atoms lie on a crystallographic mirror plane. In the crystal, the mol-ecules are linked into inversion dimers by pairs of C-H⋯F inter-actions, forming R 2 (2)(10) loops. These dimers are connected into C(6) chains along [001] through N-H⋯O hydrogen bonds. Aromatic π-π stacking inter-actions [centroid-centroid separati...
متن کامل5,10,10,15,20,20-Hexamethylcalix[4]pyrrole 5,15-diethyl diester
In the title compound, C(32)H(40)N(4)O(4), the pyrrole rings and ester groups adopt a 1,3-alternate conformation in which the alternating pyrrole and ester units are in opposite directions. The structure displays N-H⋯O hydrogen bonding and exhibits disorder [site occupancies of 0.81(2) and 0.71(2)] in the peripheral ethyl groups.
