摘要：

The unit cell contains two crystallographically independent formula units, CH6N3+.C4HO4-, that are connected via a three-dimensional network of hydrogen bonds. Two crystallographically independent anion-cation chains are formed and arranged in two crystallographically independent layers and stacked along the b axis. The guanidine molecule accepts a proton from the squaric acid. Anions and cations are nearly planar. In the anions, the C-O and especially the C-C bond lengths differ significantly, and the C-C-C angles deviate significantly from 90 degrees.
