3-Amino-benzoic acid-4,4'-bipyridine (2/3).

ABSTRACT: The asymmetric unit of the title compound, 3C(10)H(8)N(2)·2C(7)H(7)NO(2), consists of three mol-ecules of 4,4'-bipyridine (bpy) and two mol-ecules of 3-amino-benzoic acid (bza). Two mol-ecules of bza and two mol-ecules of bpy are connected via O-H?N, N-H?N and N-H?O hydrogen bonds, forming forming infinite double-stranded zigzag chains along the c axis. The third mol-ecule of bpy is linked to the chain by weak C-H?O inter-actions. Adjacent chains are linked via ?-? inter-actions [centroid-centroid distances = 3.759?(3)-3.928?(3)?Å] involving the pyridine rings of bpy mol-ecules, resulting in a sheet-like structure parallel to (100). These sheets are stacked via C-H?? inter-actions, resulting finally in the formation of a three-dimensional supra-molecular structure.

Two mol-ecules of bza and two mol-ecules of bpy are connected via O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds, forming forming infinite double-stranded zigzag chains along the c axis. The third mol-ecule of bpy is linked to the chain by weak C-H⋯O inter-actions. Adjacent chains are linked via π-π inter-actions [centroid-centro  ...[more]
