In the title compound, (C6H8N4)[AuCl4]Cl, the 4,4′-bi(1H-pyrazol-2-ium) dication, denoted [H2bpz]2+, is situated across a centre of inversion, the [AuCl4]−anion lies across a twofold axis passing through Cl—Au—Cl, and the Cl−anion resides on a twofold axis. Conventional N—H...Cl hydrogen bonding [N...Cl = 3.109 (3) and 3.127 (3) Å, and N—H...Cl = 151 and 155°] between [H2bpz]2+cations (square-planar node) and chloride anions (tetrahedral node), as complementary donors and acceptors of four hydrogen bonds, leads to a three-dimensional binodal four-connected framework with cooperite topology (three-letter notation pts). The framework contains channels along thecaxis housing one-dimensional stacks of square-planar [AuCl4]−anions [Au—Cl = 2.2895 (10)–2.2903 (16) Å; interanion Au...Cl contact = 3.489 (2) Å], which are excluded from primary hydrogen bonding with the [H2bpz]2+tectons.
