Triclinic polymorph of bis-[2-methyl-3-(pyridin-2-yl)imidazo[1,5-<i>a</i>]pyridin-2-ium] tetra-chloridocadmium(II).

ABSTRACT: The crystal structure of the title organic-inorganic hybrid salt, (C₁₃H₁₂N₃)₂[CdCl₄], (I), has been reported with four mol-ecules in the asymmetric unit in a monoclinic cell [Vassilyeva et al. (2021 ▸). RSC Advances, 11, 7713-7722]. While using two different aldehydes in the oxidative cyclization-condensation involving CH₃NH₂·HCl to prepare a new monovalent cation with the imidazo[1,5-a]pyridinium skeleton, a new polymorph was obtained for (I) in space group P1 and a unit cell with approximately half the volume of the monoclinic form. The structural configurations of the two crystallographically non-equivalent organic cations as well as the geometry of the moderately distorted te
