1,4-Bis(4-pyridylmethyl)piperazin-1-ium perchlorate fumaric acid hemisolvate
In the title salt, C(16)H(21)N(4) (+)·ClO(4) (-)·0.5C(4)H(4)O(4), fumaric acid mol-ecules, situated across crystallographic inversion centres, are O-H⋯N hydrogen bonded to two protonated 1,4-bis-(4-pyridylmeth-yl)piperazine cations, forming trimolecular units. These construct one-dimensional supra-molecular ribbons by N-H⋯N hydrogen bonding, and further aggregate via π-π inter-actions [shortest...

In the title compound, C(5)H(13)N(2) (+)·ClO(4) (-), the monoprotonated piperazine ring adopts a chair conformation. In the crystal structure, cations and anions are linked by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds into layers parallel to (01).

The asymmetric unit of the title compound, C(9)H(9)N(2) (+)·C(4)H(3)O(4) (-)·0.5C(4)H(4)O(4), consists of one 2-phenyl-imidazolium cation, one hydrogen fumarate anion and half a fumaric acid mol-ecule, which lies on an inversion center. N-H⋯O and O-H⋯O hydrogen bonds connect the cations, anions and fumaric acid mol-ecules into sheets parallel to the (102) plane.
متن کامل2-Amino-3-carboxypyrazin-1-ium perchlorate bis(2-aminopyrazin-1-ium-3-carboxylate) monohydrate
The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected b...
متن کاملPyridine-4-carbaldehyde–fumaric acid (2/1)
In the title co-crystal, 2C6H5NO·C4H4O4, two crystallographically different hydrogen-bonded trimers are formed, one in which the components occupy general positions, and one generated by an inversion centre. This results in the uncommon situation of Z = 3 for a triclinic crystal. In the formula units, mol-ecules are linked by O-H⋯N hydrogen bonds.
