Article abstract of DOI:10.1007/BF00745200

An x-ray structural study of nitrato-(m-aminobenzoato)lead (II) has been carried out (diffractometer, λMoK_α, 1123 reflections, heavy-atom method, anisotropic refinement, R = 0.096).The crystals are monoclinic, a = 13.912(3), b = 5.519(1), c = 11.932(4) Angstroem, β = 99.176(2) deg, d_calc = 2.98 g/cm³, V = 904.344 Angstroem³, Z = 4, M = 405.35, space group P2₁/n.The Pb atom is surrounded by four oxygen atoms from the COO^- groups of three organic ligands (Pb-O 2.48(3), 2.45(3), 2.84(1), 2.85(2) Angstroem), which also act as bridges between three Pb atoms, related by 2₁ symmetry.The coordination number of Pb is brought up to nine by four oxygen atoms from two NO3^- anions (Pb-O 2.79(3), 2.94(2), 2.94(2), 2.92(2) Angstroem, and one nitrogen atom of an amino group (Pb-N 2.57(2) Angstroem).
