Reaction of Ti(OBu)4 or Zr(OBu)4 with tbutyl-calix[4]arene, calixtBu(OH)4, led to the formation of Ti2(OBu)2[calixtBuO3(OH)]2 and Zr3(OBu)8(calixtBuO4), respectively. Upon in situ generation of water in the reaction with Zr(OBu)4, the partially hydrolyzed compound Zr4O(OBu)6(calixtBuO4)2(BuOH)2 was isolated.
