LEWIS-BASE ADDUCTS OF LEAD(II) COMPOUNDS V,* SYNTHESIS AND STRUCTmAL CHARACTEREATION OF MONONUCLEAR (ACETATO-0,O') BIS(2,Zr-BIPYRIDINE) (PERCHLORATO-0,O') LEAD(II) AND BIS (2,Z'-BIPYRIDIW) BIS(PERCHL0RATO-0,O') LEAD(II)

Abstract
The synthesis and single-crystal X-ray structure determination of the title compound [(bipy) , Pb(0 ,CMe) (O ClO )] (1) and [(bipy) Pb(ClO ) ] (2) is described.
Compound (I) crystallizes in the triclinic space group P1(2), a= 7.384(2), b=
12.824(3), c= 10.622(6) A, ?= 73.41(2), ?= 80.98(2), ?= 73.68(2)', Z= 2, and R =0.033 for 3408 independent reflections .Compound (2) crystallizes in the monoclinic space group P2 /n(14), a= 6.883(5), b= 13.010(4), c= 10.710(5)?,?= 91.26(2)? Z=2, and R= 0.048 for 3290 independent reflections
