5,10,10,15,20,20-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.
متن کاملDimethyl 3,5-diethyl-1H-pyrrole-2,4-dicarboxylate
The title pyrrole derivative, C(12)H(17)NO(4), consists of a pyrrole ring with two diagonally attached meth-oxy-carbonyl groups and two diagonally attached ethyl groups. The two carbonyl groups are approximately in the same plane as the pyrrole ring, making dihedral angles of 3.50 (19) and 6.70 (19)°. In the crystal, adjacent mol-ecules are assembled into dimers in a head-to-head mode by pairs ...
متن کاملDibenzyl 3,3′-diethyl-4,4′-dimethyl-2,2′-methylenebis(pyrrole-5-carboxylate)
In the title compound, C(31)H(34)N(2)O(4), the two pyrrole rings are bent around the central methyl-ene C atom, making a dihedral angle of 64.83 (7)°. In the crystal, mol-ecules are linked into dimers via N-H⋯O=C hydrogen bonds. These dimers are packed through π⋯π inter-actions between neighboring pyrrole rings with a separation between the mean planes of symmetry-related pyrrole rings of 3.61 ...
متن کاملDiethyl 2-amino-5-[(E)-(1-methyl-1H-pyrrol-2-yl)methylideneamino]thiophene-3,4-dicarboxylate
The structure of the title compound, C(16)H(19)N(3)O(4)S, shows the planes described by the thio-phene and the pyrroles are twisted by 17.06 (4)°. Additionally, the structure shows the azomethine bond adopts the E configuration, while the pyrrole is disordered as a heterocycle flip [occupancy ratio 0.729 (5):0.271 (5)]. The three-dimensional network is well packed and involves N-H⋯O hydrogen bo...
متن کاملDiethyl 5,5′-thiobis[2-amino-4-(4-fluorophenyl)-1-phenyl-1H-pyrrole-3-carboxylate]
In the title compound, C(38)H(32)F(2)N(4)O(4)S, the ethyl chain of the ethoxy-carbonyl group displays rotational disorder with site occupancy factors ca 0.6 and 0.4. The S atom lies on a twofold rotation axis. There are both inter- and intra-molecular hydrogen bonds in the crystal structure. An intra-molecular N-H⋯O hydrogen bond forms a six-membered ring, while an inter-molecular N-H⋯F hydroge...
