The crystals of tetralead hexanitrate ethylenediaminetetraacetatoplumbate(II) tetrahydrate Pb₄(NO₃)₆[PbC₁₀H₁₂O ₈]·4H₂O were synthesized and studied by X-ray diffraction (MoK_α radiation, 2388 reflections, R_F = 0.0376, R_W = 0.0348). The orthorhombic unit cell (space group Fdd2, a = 18.995(2), b = 40.649(4), c = 8.5178(8) Å, Z = 8) contains 16 complex cations [Pb₂(NO₃)₃]²⁺, 8 complex anions [Pb(Edta)]^2-, and 32 crystallization water molecules. The organic and inorganic fragments alternating along the y axis are united into a single frame by the bridging oxygen atoms and by hydrogen bonds. The (Edta)^4- ligand, forming one ethylenediamine metallocycle and four glycinate ones, is compressed in the axial direction and stretched in the equatorial direction. The coordination polyhedron of the Pb cation bound with the ligand is a strongly distorted trigonal antiprism. The inorganic fragment is a close-packed double layer of Pb atoms linked with each other by NO₃ groups. Thus lead atoms perform a dual function in the structure, forming both complex anions and outer-spheric cations.
