Diethyl 2-[(4-bromoanilino)methylidene]malonate
In the title compound, C(14)H(16)BrNO(4), inter-molecular C-H⋯O hydrogen bonds link the mol-ecules, forming a stable structure. An intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring and helps to establish the mol-ecular conformation which is almost planar, with an r.m.s deviation of 0.0842 Å.

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.

The asymmetric unit of the title compound, C(18)H(22)N(2)O(3)S, contains two mol-ecules, exhibiting similar conformations [C-S-N-C torsion angles of -82.2 (2) and -70.4 (2)°, and dihedral angles between the mean planes of the aromatic rings of 56.6 (6) and 51.6 (6)° in mol-ecules I and II, respectively]. However, the two independent mol-ecules show distinctly different hydrogen-bonding patterns...

In the title compound, C(25)H(27)NO(7), the pyrrolidine ring exhibits an envelope conformation and the benzene rings form a dihedral angle of 33.47 (11)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. Weak C-H⋯O inter-actions link the dimers into layers parallel to the bc plane.
متن کاملDiethyl [(4-nitrobenzamido)(phenyl)methyl]phosphonate
In the title compound, C18H21N2O6P, the dihedral angle between the benzene and phenyl rings is 85.1 (2)°. In the crystal, mol-ecules are linked via pairs of N-H⋯O(=P) hydrogen bonds, forming inversion dimers with graph-set notation R 2 (2)(10). One of the ethyl groups is disordered over two sets of sites, with occupancies 0.746 (11) and 0.254 (11).
