Abstract

In 1-(2-iodo­benzo­yl)-4-(pyrimidin-2-yl)piperazine, C15H15IN4O, the central piperazine ring adopts an almost perfect chair conformation with the pyrimidine substituent in an equatorial site. The planar amide unit makes a dihedral angle of 80.44 (7)° with the phenyl ring. A combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the mol­ecules into a complex three-dimensional network structure, augmented by a π–π stacking inter­action and an I⋯N halogen bond, all involving different pairs of inversion-related mol­ecules. Comparisons are made with the structures of a number of related compounds.
