Abstract
The crystal structure of lead(II) diethyldithiocarbamate has been determined by X-ray methods. The crystal is monoclinic, with the space group Co; a=16.614+5, b=11.781+4, c=9.351+_4 A, fl= 117 "̀ 732' +_ 5' and Z = 4. Two carbamate ions are coordinated to the central metal atom through sulphur atoms, forming a monomeric complex molecule of bis(diethyldithiocarbamato)lead(II), [Pb(S2CNEt2)2]. Four Pb-S distances are 2.744, 2.786, 2.885 and 2.940 A (errors: ~0.010 A), and one ligand is closer to the lead atom than another by about 0.05 /~,. The complex molecule assumes a strongly distorted pyramidal configuration. The angle S-Pb-S involving two shorter bonds is 96.2 °, while the longer bonds make an angle of 133.2 °. This structure is closely related to that of the yellow form of PbO. 507
