Novel heteroscorpionate-containing tin and organotin(IV) complexes, [SnRnX3 − n(L)], R = Me, Bun, 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, 1H, 13C and 119Sn NMR, 119mSn Mössbauer) 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 BunSnCl3, PhSnCl3 and SnCl4 in Et2O in the absence of base, yielding 1:1 adducts [XSnCl3(bpzaH)] (X = R or Cl).
Bis(pyrazol-1-yl)acetate ligands react with tin(IV) and organotin(IV) acceptors affording 1:1 fac-octahedral derivatives, characterized in the solid state and solution. Neutral bis(pyrazol-1yl)acetic acid reacts with monorganotin(IV) and tin(IV) chloride in the absence of base yielding 1:1 octahedral adducts, where only nitrogen atoms of bis(pyrazol-1-yl)acetate are coordinated to tin.Figure optionsDownload as PowerPoint slide
