1-[(4-Methylbenzylidene)amino]-5-(4-methylbenzoyl)-4-(p-tolyl)pyrimidin-2(1H)-one

Abstract

In the title mol­ecule, C27H23N3O2, the three benzene rings make dihedral angles of 84.4 (1), 36.6 (1) and 59.3 (1)° with the central pyrimidine ring. In the crystal structure, mol­ecules associate into centrosymmetric dimers via weak C—H⋯O hydrogen‐bonding inter­actions.

Crystal Structure of 5-(4-Methylbenzoyl)-1-(methyl-4-methylphenyl-methylene amino)-4-(4-methylphenyl)-1H-pyrimidine-2-thione

“…The molecular structure of the title compound is closely related to that of 5-(4-methylbenzoyl)-4-(4-methylphenyl)-1-(methylphenyl-methylenamino)-1H-pyrimidin-2-one and 1-[(4-methylbenzylidene)amino]-5-(4-methylbenzoyl)-4-(ptolyl)pyrimidin-2(1H)-one. 5,6 The pyrimidine ring is slightly distorted from planarity with a maximum deviation of -0. …”
