Abstract

Reaction of Ti(OR)4 or Zr(OR)4 with carboxylic acids resulted in the formation of crystalline carboxylate-substituted oxotitanium and oxozirconium clusters with different Ti/Zr : carboxylate ratios. Structural investigations showed that the cluster cores are rutile- or zirconia-like if the carboxylate : metal ratio does not exceed 1.33 (for Ti) or 2 (for Zr), respectively. When the carboxylate : metal ratio is increased beyond these values, more open clusters and eventually polymeric structures are obtained.
