Methyl N-({[2-(2-meth-oxy-acetamido)-4-(phenyl-sulfan-yl)phen-yl]amino}[(meth-oxy-carbonyl)imino]methyl)carbamate.

Abstract: In the title compound, C20H22N4O6S, the phenyl and benzene rings form a dihedral angle of 58.75 (5)°. Intra­molecular N—H⋯O and N—H⋯N hydrogen bonds generate two S(6) and one S(7) ring motif, respectively. In the crystal, mol­ecules are linked via N—H⋯O, N—H⋯N, C—H⋯S and C—H⋯O hydrogen bonds, forming two-dimensional networks parallel to the bc plane.

3‐[4‐(Methylsulfanyl)benzyl]‐4‐{(1E)‐[4‐(methylsulfanyl)phenyl]methyleneamino}‐4,5‐dihydro‐1H‐1,2,4‐triazole‐5‐thione

Abstract: Geometric parameters of the title compound, C18H18N4S3, are in the usual ranges. The triazole ring makes dihedral angles of 75.00 (5) and 38.51 (7)degrees with the two aromatic rings. The molecules crystallize as centrosymmetric dimers connected by N-H center dot center dot center dot S hydrogen bonds.

Crystal structure of 4-[(E)-(4-chloro­benzyl­idene)amino]-3-(2-methyl­benz­yl)-1H-1,2,4-triazole-5(4H)-thione

Abstract: In the title mol-ecule, C17H15ClN4S, the benzene rings form dihedral angles of 16.6 (1) and 77.2 (1)° with the triazole ring. The dihedral angle between the benzene rings is 86.6 (1)°. In the crystal, pairs of N-H⋯S hydrogen bonds form inversion dimers with graph-set notation R 2 (2)(8). Weak C-H⋯S hydrogen bonds link these dimers into layers parallel to (100). Weak intra-molecular C-H⋯S and C-H⋯N contacts are observed.

(2E)-3-(Biphenyl-4-yl)-1-(4-methoxyphenyl)prop-2-en-1-one

Abstract: The title compound, C22H18O2, was prepared from biphenyl-4-carbaldehyde and 4-methoxyacetophenone. The molecule deviates significantly from planarity.

Ethyl 6-methoxy-2-naphthoate

Abstract: The title compound, C14H14O3, is a starting compound for the synthesis of non-steroidal anti-inflammatory drugs and is an important substrate in the pharmaceutical industry. Whereas the meth­oxy group is almost coplanar with the naphthyl ring system, the eth­oxy group is significantly twisted out of the plane of the aromatic system [C—O—C—C = −85.31 (15)°].
