In the crystal, anion¨Canion O¡ªH...O hydrogen bonds and weak O¡ªH...O interactions form infinite chains along [100]. Between these chains, cation¨Canion N¡ªH¡ªO hydrogen bonds are observed, forming an alternate pattern of cation and anion layers and leading to a two-dimensional network parallel to (100). %U http://scripts.iucr.org/cgi-bin/paper?S1600536813001207
