Tris(1H-benzimidazol-3-ium-2-ylmeth-yl)amine tris-(2,4,6-trinitro-phenolate) acetonitrile disolvate.

In the cation of the title salt, C(24)H(24)N(7) (3+)·3C(6)H(2)N(3)O(7) (-)·2C(2)H(3)N, the three benzimidazolium ring systems are oriented to each other at dihedral angles of 10.42 (7), 23.98 (7) and 22.

Bis[N,N-bis-(1-allyl-1H-benzimidazol-2-ylmethyl-κN)benzyl-amine-κN]cadmium dipicrate.

The crystal structure of the title compound, [Cd(C(29)H(29)N(5))(2)](C(6)H(2)N(3)O(7))(2), consists of Cd(II) complex cations and picrate anions. In the complex cation, the Cd(II) ion is chelated by two bis-(1-allyl-benzimidazol-2-ylmeth-yl)benzyl-amine (babb) ligands in a distorted octa-hedral geometry. Extensive C-H⋯O hydrogen bonding occurs between cations and anions in the crystal structure.

Bis(nitrato-κO)(3-oxapentane-1,5-diamine-κN,O,N')zinc(II).

In the title compound, [Zn(NO(3))(2)(C(4)H(12)N(2)O)], the Zn(II) atom is N,O,N'-chelated by a 3-oxapentane-1,5-diamine ligand and is further coordinated by two nitrate anions in a distorted trigonal-bipyramidal geometry. Inter-molecular N-H⋯O hydrogen bonding is present in the crystal structure. A short O⋯O contact of 2.
