The title compound, C18H20ClN3S, is a functionalized triazoline-3-thione derivative. The benzene ring is almost perpendicular to the planar 1,2,4-triazole ring [maximum deviation = 0.007 (1) Å] with a dihedral angle of 89.61 (5)° between them and there is an adamantane substituent at the 3-position of the triazolethione ring. In the crystal, N—H...S hydrogen-bonding interactions link the molecules into chains extending along thec-axis direction. The crystal packing is further stabilized by weak C—H...π interactions that link adjacent chains into a two-dimensional structure in thebcplane. The crystal studied was an inversion twin with a 0.50 (3):0.50 (3) domain ratio.

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.

In the racemic title compound, C17H15ClN2O4, which has been synthesized and the crystal structure of the solvent-free molecule determined, the angle between the planes of the benzene and cyclopropane rings is 54.29 (10)°. The molecular conformation is stabilized by two weak intramolecular C—H...Ocarboxylinteractions. In the crystal, C—H...O hydrogen bonds form centrosymmetric cyclicR22(10) dimers which are linked into chain substructures extending alongc. Further C—H...Nnitrilehydrogen bonding, including a centrosymmetric cyclicR22(14) association, link the chain substructures, forming a two-dimensional layered structure extending across the approximateabplane. No significant π–π or halogen–halogen intermolecular interactions are present in the crystal.
