Crystal structure and void analysis of tris-(2-amino-1-methyl-benzimidazolium) hexa-kis-(nitrato-κ ,')lanthanate(III).

The organic-inorganic complex salt, (CHN)[La(NO)], comprises a network of N-protonated 2-amino-1-methyl-benzimidazolium cations and hexa-kis-(nitrato)lanthanate(III) anions. The La atom is twelve-coordinate within a distorted icosa-hedral environment. In the unit cell, each pair of the La atoms lie nearly on one of the crystallographic glide planes.
