4-Chloroselanyl-3,5-diethyl-1H-pyrazol-2-ium chloride
In the cation of the title compound, C(7)H(12)ClN(2)Se(+)·Cl(-), the ethyl-ene groups and the Se-Cl fragment adopt a cis configuration with a C-Se-Cl angle of 96.09 (6)°. In the crystal, inter-molecular N-H⋯Cl hydrogen bonds link two cations and two chlorine anions into centrosymmetric clusters. π-π inter-actions between the pyrazole rings [centroid-centroid distance of 3.530 (2) Å] link these ...
متن کاملBis{4-[(3,5-dimethyl-1H-pyrazol-4-yl)selanyl]-3,5-dimethyl-1H-pyrazol-2-ium} chloride monohydrate
In the title compound, 2C(10)H(15)N(4)Se(+)·Cl(-)·OH(-), a singly protonated mol-ecule of the organic selenide participates in hydrogen bonding with neighboring mol-ecules, forming zigzag chains along [001]. The molecule adapts a cis bridging mode with a C-Se-C angle of 102.13 (15)°. π-π stacking inter-actions are observed between the closest pyrazole rings of neighboring chains [centroid-centr...
متن کامل3-Ethyl-4-methyl-1H-pyrazol-2-ium-5-olate
The title compound, C(6)H(10)N(2)O, is a zwitterionic pyrazole derivative. The crystal packing is predominantly governed by a three-center iminium-amine N(+)-H⋯O(-)⋯H-N inter-action, leading to an undulating sheet-like structure lying parallel to (100).
متن کامل1H-Pyrazol-2-ium hydrogen oxalate
In the title compound, C(3)H(5)N(2) (+)·C(2)HO(4) (-), the anions form centrosymmetric dimers through cyclic O-H⋯O hydrogen-bonding associations [graph set R(2) (2)(10)]. These dimers are then linked through a cyclic R(4) (2)(10) N-H⋯O hydrogen-bonding association involving two cations and the carboxyl O-atom acceptors of separate anions, giving chain structures extending across the (111) plane.
متن کامل3-Amino-1H-pyrazol-2-ium trifluoroacetate
The asymmetric unit of the title salt, C3H6N3 (+)·C2F3O2 (-), contains two independent 3-amino-pyrazolium cations and two independent tri-fluoro-acetate anions. The F atoms of both anions were refined as disordered over two sets of sites, with common occupancy ratios of 0.639 (12):0.361 (12). In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming chains along [100] ...
