Abstract

The asymmetric unit includes two crystallographically independent equivalents of the title salt, C6H7N2O2+·ClO4−. The cations and anions form separate layers alternating along the c axis, which are linked by N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds into a two-dimensional network parallel to (100). Further C—H⋯O contacts connect these layers, forming a three-dimensional network, in which R44(20) rings and C22(11) infinite chains can be identified.
