Crystal structure and Hirshfeld surface analysis of 2-phenyl-1-phenanthro[9,10-]imidazol-3-ium benzoate.

In the title compound, CHN ·CHO , 2-phenyl-1-phenanthro[9,10-]imidazole and benzoic acid form an ion pair complex. The system is consolidated by hydrogen bonds along with π-π inter-actions and N-H⋯π inter-actions between the constituent units. For a better understanding of the crystal structure and inter-molecular inter-actions, a Hirshfeld surface analysis was performed.

Crystal structure, DFT and MEP study of ()-2-{[(3-chloro-phen-yl)imino]-meth-yl}-6-methyl-phenol.

In the crystal structure of the title compound, CHClNO, the mol-ecules are linked through C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming chains parallel to the [010] direction. π-π inter-actions and intra-molecular hydrogen bonds are also observed. The mol-ecular geometry of the title compound in the ground state has been calculated using density functional theory at the B3LYP level with the 6-311++G(2,2) basis set.
