title: Metronidazolium perchlorate.
abstract: IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium perchlorate], C(6)H(10)N(3)O(3) (+)·ClO(4) (-), the cations are linked by inter-molecular N-H⋯O hydrogen bonds into zigzag chains along the c axis. The cations and anions are connected by O-H⋯O and C-H⋯O hydrogen bonds. A weak intra-molecular C-H⋯O hydrogen bond is also observed.
