In the title compound, C(9)H(9)N(2)OS(+).Cl(-), the cations exhibit amidinium-type delocalization of the positive charge. The ions are linked by one O-H.Cl hydrogen bond and two N-H.Cl hydrogen bonds into chains of edge-fused R(4)(2)(11) rings. The chains are linked into sheets by a pi-pi stacking interaction.
在标题化合物C(9)H(9)N(2)OS(+)·Cl(-)中,阳离子呈现出正电荷的脒型离域。离子通过一个O-H…Cl氢键和两个N-H…Cl氢键连接成边缘稠合的R(4)(2)(11)环链。这些链通过π-π堆积相互作用连接成片。
