4-Chloro-selanyl-3,5-diethyl-1H-pyrazol-2-ium chloride.

ABSTRACT: 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 clusters into columns along [001] with short inter-molecular Se⋯Cl(-) contacts of 2.995 (1) Å.

Bis{4-[(3,5-dimethyl-1H-pyrazol-4-yl)selan-yl]-3,5-dimethyl-1H-pyrazol-2-ium} chloride monohydrate.

Project description: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-centroid distance = 3.888 (1) Å] and hydrogen bonding occurs through bridging chloride anions and hydroxide groups. Additionally, O-H⋯Cl hydrogen bonds are formed.

1-(3,5-Diethyl-1H-pyrazol-1-yl)-3-phenyl-isoquinoline.

Project description:In the title mol-ecule, C(22)H(21)N(3), the isoquinoline ring is almost planar [maximum deviation = 0.046 (1) Å] and makes dihedral angles of 52.01 (4) and 14.61 (4)° with the pyrazole and phenyl rings, respectively. The phenyl ring and the pyrazole ring are twisted by 44.20 (6)° with respect to each other. The terminal C atoms of both of the ethyl groups attached to the pyrazole ring are disordered over two sites with occupancy ratios of 0.164 (7):0.836 (7) and 0.447 (16):0.553 (16). A weak intra-molecular C-H⋯N contact may influence the mol-ecular conformation. The crystal structure is stabilized by C-H⋯π contacts involving the phenyl and pyrazole rings, and by π-π stacking inter-actions involving the pyridine and benzene rings [centroid-centroid distance = 3.5972 (10) Å].

Diethyl 4-[5-(4-chloro-phen-yl)-1H-pyrazol-4-yl]-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:In the title compound, C(22)H(24)ClN(3)O(4), intra-molecular C-H⋯O and C-H⋯N hydrogen bonds form S(9) and S(7) ring motifs, respectively. The 1,4-dihydro-pyridine ring adopts a flattened boat conformation. The benzene ring makes a dihedral angle of 33.36 (6)° with the pyrazole ring. In the crystal, pairs of N-H⋯N hydrogen bonds link the mol-ecules into inversion dimers. The dimers are stacked in column along the a axis through N-H⋯O and C-H⋯N hydrogen bonds. The crystal packing also features C-H⋯π inter-actions involving the pyrazole ring.
