Crystal structure and void analysis of tris­(2-amino-1-methyl­benzimidazolium) hexa­kis­(nitrato-κ(2) O,O′)lanthanate(III)

The organic–inorganic complex salt, (C(8)H(10)N(3))(3)[La(NO(3))(6)], comprises a network of N-protonated 2-amino-1-methyl­benzimidazolium cations and hexa­kis­(nitrato)lanthanate(III) anions. The La(III) atom is twelve-coordinate within a distorted icosa­hedral environment. In the unit cell, each pair of the La(III) atoms lie nearly on one of the crystallographic glide planes. In the crystal structure, there are several N—H⋯O hydrogen-bonding inter­actions between the cations and terminal oxygen atoms from the nitrate moieties of the [La(NO(3))(6)](3–) anion. Additional weak C—H⋯O hydrogen bonds between the cations and anions consolidate the three-dimensional arrangement of the structure. A packing analysis was performed to check the strength of the crystal packing.
