1-Methyl-4-(4-nitrobenzoyl)pyridinium perchlorate
In the main mol-ecule of the title compound, C(13)H(11)N(2)O(3) (+)·ClO(4) (-), the two aromatic rings are twisted by 56.19 (3)° relative to each other and the nitro group is not coplanar with the benzene ring [36.43 (4)°]. The crystal packing is dominated by infinite aromatic stacks in the a-axis direction. These are formed by the benzene units of the mol-ecule featuring an alternating arrange...
متن کامل3-Acetyl-6-chloro-2-methyl-4-phenylquinolinium perchlorate
In the title mol-ecular salt, C(18)H(15)ClNO(+)·ClO(4) (-), the quinolin-ium ring system is approximately planar, with a maximum deviation of 0.027 (1) Å. The dihedral angle formed between the mean planes of the quinolinium ring system and the benzene ring is 78.46 (3)°. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the cations and anions into a three-dimensional...

In the unsymmetrical title complex, [Ni(C(20)H(23)N(4)O(4))]ClO(4), the coordination geometry for the Ni(II) atom can be described as square planar. The aromatic rings in the two ligands are almost vertical, with a dihedral angle of 85.3°. In the crystal, cations and anions are linked by weak C(N)-H⋯O hydrogen bonding.
متن کامل2-(2-Chlorophenyl)-5-methyl-1,3-dioxane-5-carboxylic acid
In the title compound, C(12)H(13)ClO(4), the 1,3-dioxane ring adopts a chair conformation and the 2-chloro-benzene and methyl substituents occupy equatorial sites. The carboxyl group is in an axial inclination. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
متن کاملDesign and Synthesis of 2-Methyl and 2-Methyl-4-Nitro Imidazole Derivatives as Antifungal Agents
Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...
