چکیده
The asymmetric unit of the title co-crystal, C12H14N4O2S·0.5C6H12N2, comprises the sulfonamide mol-ecule and half a mol-ecule of 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO), the latter being disposed about a crystallographic twofold rotation axis. In the sulfonamide mol-ecule, the aromatic rings are almost perpendicular to one another [dihedral angle = 75.01 (8)°]. In the crystal, mol-ecules are connected into a three-mol-ecule aggregate via amide-DABCO N-H⋯N hydrogen bonds, and these are connected into a three-dimensional architecture via amino-DABCO N-H⋯O and amino-pyrimidine N-H⋯N hydrogen bonds.

In the title salt C6H14N2 (2+)·2C7H4ClO2 (-), two 3-chloro-benzoate (3CBA) anions are bridged by one diprotonated 1,4-di-aza-bicyclo-[2.2.2]octane-1,4-diium (H2DABCO(2+)) dication through N-H⋯O hydrogen bonds. In this way, a trimeric unit is generated, in which the mean planes of the two 3CBA anions are twisted with respect to each other by a dihedral angle of 59.87 (9)°. The trimeric units are...

The title compound, C(18)H(28)N(5)O(2) (+)·I(-), was observed as a main product in an intended 1:1 reaction between 4-iodo-nitro-benzene and 1,4-diaza-bicyclo-[2.2.2]octane (DABCO). In the reaction, DABCO undergoes a ring opening to yield a quaternary salt of DABCO and 1-ethyl-4-(4-nitro-phen-yl)piperazine with an iodide anion. The crystal structure determination was carried out as no crystal s...

The 1:1 co-crystallization of 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO) with 4-nitro-benzoic acid in ethanol-water (3/1) gave the salt dihydrate C6H13N2 (+)·C7H4NO4 (-)·2H2O, (1), whereas from methanol, the salt C6H14N2 (2+)·2C7H4NO4 (-), (2), was isolated. In (1), the cation and anion are linked by a strong N-H⋯O hydrogen bond, and the carboxyl-ate anion is close to planar [dihedral angle betwe...
