摘要：

Novel heteroscorpionate-containing tin and organotin(IV) complexes, [SnRnX3-n(L)], R = Me, Bu-n, Ph, or cy; X = Cl, Br or I, n = 0, 1, 2 or 3; L = bis(pyrazol-1-yl)acetate (bpza) or bis(3,5-dimethylpyrazol-1-yl)acetate (bdmpza), have been synthesized and characterized by spectral (IR, H-1, C-13 and Sn-119 NMR, Sn-119m Mossbauer) and analytical data. In [SnI3(bdmpza)], the ligand is fac-N,N',O-tridentate, the three iodine atoms thus also fac about the six-coordinate tin(IV) atom. Neutral bpzaH reacts with (BuSnCl3)-Sn-n, PhSnCl3 and SnCl4 in Et2O in the absence of base, yielding 1:1 adducts [XSnCl3(bpzaH)] (X = R or Cl). (c) 2005 Elsevier B.V. All rights reserved.
