A series of triarylantimony dichrysanthemate compounds of the type Ar 3 Sb(O 2 CR) 2 [Ar=C 6 H 5 , 4‐CH 3 C 6 H 4 , 3‐CH 3 C 6 H 4 , ‐CH 3 C 6 H 4 , 4‐ClC 6 H 4 ; R=4‐ClC 6 H 4 CH(i‐Pr),cis ‐Cl 2 C:CHtrans ‐Cl 2 C:CH] have been synthesized and characterized by elemental analysis, infrared spectra, 1 H NMR spectra and mass spectra. Some activities of these compounds in plant growth regulation have been determined. Their results indicate that the derivatives of cis ‐dichlorochrysanthemic acid and trans ‐dichlorochrysanthemic acid significantly promote rooting of excised cucumber cotyledons at 10 ppm. An X ray structure determination has been carried out as follows for Ph 3 Sb(O 2 CCHCMe 2 CMe 2 ) 2 : orthorhombic, space group Pbcn , Z =4, structure solution with 2385 independent reflections, R =0.035. Lattice dimensions at 26 °C: a =15.616(3) Å, b =10.275(2) Å, c =20.201(5) Å, V =3241(2) Å 3 , ρ=1.302 g cm −3 . © 1998 John Wiley & Sons, Ltd.
