title: Crystal structure of 2,2-di-phenyl-hydrazinium chloride.
abstract: In the title compound, C12H13N2 (+)·Cl(-), the chloride salt of 1,1'-di-phenyl-hydrazine, the phenyl rings are inclined to one another by 78.63 (17)°. The N-(+)NH3 bond lengths is 1.445 (3) Å, and the N-Cphen-yl bond lengths are 1.435 (3) and 1.447 (4) Å. In the crystal, mol-ecules are linked via N-H⋯Cl hydrogen bonds, forming chains along [10-1], which enclose two adjacent R (4) 2(6) ring motifs. The chains are reinforced by C-H⋯Cl hydrogen bonds.
