(Nitrato-κO){N,N,N′,N′-tetra­kis­[(1H-benzimidazol-2-yl-κN (3))meth­yl]cyclo­hexane-1,2-diamine}­lead(II) hemiaqua­{N,N,N′,N′-tetra­kis­[(1H-benzimidazol-2-yl-κN (3))meth­yl]cyclo­hexane-1,2-diamine}­lead(II) trinitrate dihydrate

In the title compound, [Pb(NO(3))(C(38)H(38)N(10))][Pb(C(38)H(38)N(10))(H(2)O)(0.5)](NO(3))(3)·2H(2)O, both Pb(II) ions are coordinated in a distorted trigonal–prismatic environment by a hexa­dentate N,N,N′,N′-tetra­kis­[(1H-benzimidazol-2-yl)meth­yl]cyclo­hex­ane-1,2-diamine ligand. A nitrate and a half-occupancy water ligand form long coordination bonds to the Pb(II) ions capping the trigonal–prismatic environment. In the crystal, the components are linked by N—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional network. C—H⋯O inter­actions also occur.
