title: (Nitrato-κO){N,N,N',N'-tetra-kis-[(1H-benzimidazol-2-yl-κN)meth-yl]cyclo-hexane-1,2-diamine}-lead(II) hemiaqua-{N,N,N',N'-tetra-kis-[(1H-benzimidazol-2-yl-κN)meth-yl]cyclo-hexane-1,2-diamine}-lead(II) trinitrate dihydrate.
abstract: 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 hexa-dentate N,N,N',N'-tetra-kis-[(1H-benzimidazol-2-yl)meth-yl]cyclo-hex-ane-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 inter-actions also occur.
