摘要

In the title compound, [Pb(NO3)(C38H38N10)][Pb(C38H38N10)(H2O)0.5](NO3)3·2H2O, 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.
