Synthesis, structural studies and Hirshfeld surface analysis of 2-[(4-phenyl-1H-1,2,3-triazol-1-yl)methyl]pyridin-1-ium hexakis (nitrato-κ²O,O′)thorate(IV).

Reaction of thorium(IV) nitrate with 2-[(4-phenyl-1H-1,2,3-triazol-1-yl)meth­yl]pyridine (L) yielded (LH)₂[Th(NO₃)₆] or (C₁₄H₁₃N₄)₂[Th(NO₃)₆] (1), instead of the expected mixed-ligand complex [Th(NO₃)₄L₂], which was detected in the mass spectrum of 1. In the structure, the [Th(NO₃)₆]²⁻ anions display an icosa­hedral coordination geometry and are connected by LH⁺ cations through C—H⋯O hydrogen bonds. The LH⁺ cations inter­act via N—H⋯N hydrogen bonds. Hirshfeld surface analysis indicates that the most important inter­actions are O⋯H/H⋯O hydrogen-bonding inter­actions, which represent a 55.2% contribution. [ABSTRACT FROM AUTHOR]
