Popis:	The structures of the complexes [PbL 2 ], L = 1-phenyl-3-methyl-4-acylpyrazolonato, RCOC 10 H 8 N 2 O, R = Me ( 2 ) or Pr ( 3 ), have been determined by X-ray diffraction studies. Compound 2 is monoclinic, space group P2 1 , a = 11.285(4), b = 14.727(4), c = 20.749(5) A , β = 95.83(3)°, R = 0.039 for 4486 reflections, and 3 is monoclinic, space group C2/c, a = 27.528(11), b = 7.245(11), c = 14.264(7) A , β = 113.6(3)°, R = 0.021 for 2118 reflections. There are three different lead environments in 2 but only one in 3 . In each case the lead atom makes four strong bonds to oxygen and two weaker bonds to either oxygen or nitrogen in adjacent molecules.
