Pyrrolidinium chloride [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
The title compound, C(4)H(10)N(+)·Cl(-), was obtained as a decomposition product from 2,6-bis-(pyrrolidin-yl)pyridine. The anion lies on the same cristallographic mirror plane as the N atom of the cation, the complete cation being generated by mirror symmetry.

Triphenyltellurium chloride [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2014
The asymmetric unit of the title compound, C18H15ClTe, contains two molecules which are in inverted orientations. The compound displays a tetrahedral geometry around the Te atom in spite of there being five electron domains. This is attributed to the fact that the lone pair is not sterically active.

Tribenzylammonium chloride [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2014
Single crystals of the title salt, C21H21NH+·Cl−, were isolated as a side product from the reaction involving [(C6H5CH2)3NH]2[HPO4] and Sn(CH3)3Cl in ethanol. Both the cation and the anion are situated on a threefold rotation axis. The central N atom in the cation has a slightly distorted tetrahedral environment, with angles ranging from 107.7 to 111 ...
