Molecular zinc phosphonates: synthesis and X-ray crystal structures of [{(ZnMe)4(THF)2}{tBuPO3}2] and [{(ZnEt)3(Zn(THF))3}{tBuPO3}43-OEt}]

Abstract

The reactions of zinc alkyls with tert-butylphosphonic acid in 2 ∶ 1 and 1 ∶ 1 molar ratios afforded [{(ZnMe)4(THF)2}{tBuPO3}2] (2) and [{(ZnEt)3(Zn(THF))3}{tBuPO3}43-OEt}] (3), respectively. Compounds 2 and 3 have been fully characterised by means of spectroscopic and analytical methods. Single-crystal X-ray diffraction studies revealed that zinc phosphonates 2 and 3 are tetra- and hexa-nuclear, respectively. This is in contrast to the dodecanuclear zinc phosphonate [{Zn2(THF)2(ZnEt)6Zn44-O)}{(tBuPO3)8}] (1) obtained in a 1.5 ∶ 1 reaction between zinc alkyls and tBuP(O)(OH)2.
