Structural analysis of 2-iodo-benzamide and 2-iodo-N-phenyl-benzamide.

ABSTRACT: The title compounds, 2-iodo-benzamide, C7H6INO (I), and 2-iodo-N-phenyl-benzamide, C13H10INO (II), were both synthesized from 2-iodo-benzoic acid. In the crystal structure of (I), N-H⋯O and hydrogen bonds form two sets of closed rings, generating dimers and tetra-mers. These combine with C-I⋯π(ring) halogen bonds to form sheets of mol-ecules in the bc plane. For (II), N-H⋯O hydrogen bonds form chains along the a-axis direction, while inversion-related C-I⋯π(ring) contacts supported by C-H⋯π(ring) interactions generate sheets of mol-ecules along the ab diagonal.
