Crystal structure of Bis(thiourea) lead(II) nitrate Pb(NO3)2 · [SC(NH2)2]2*

Abstract

Abstract The crystal structure of bis(thiourea) lead(II) nitrate (monoclinic; a = 7.212(1) Å, b = 17.952(2) Å, c = 9.475(1) Å, β = 108.6(1)°, Z = 4, space group P21/c) has been determined from the intensities of 2143 independent reflections measured from a spherically ground crystal (graphite-monochromated MoKα; 4-circle diffractometer; R = 6.3%). The structure is described in terms of zig-zag chains of composition [Pb(tu)2]2 + running in the [100] direction; the Pb(II) moieties are linked through S atoms by pairs of thiourea molecules. In addition five oxygen atoms of three NO3 − ions are coordinated to each Pb(II) moiety. There is hydrogen bonding between thiourea molecules, and between thiourea molecules and NO3 − ions.
