A series of bismuth(III) and antimony(III) complexes supported by silicon-containing calix[5]arene ligands were synthesized and fully characterized by NMR, X-ray, IR, mp, UV/vis, and elemental analysis. Reaction of the para-tert-butylcalix[5]arene [tBuC5(H)5] disodium salt, Na2·tBuC5(H)3, with 1 equiv of R2SiCl2 (R = Me, iPr, Ph, CH═CH2) or treatment of the tBuC5(H)5 lower rim monobenzyl ether [tBuC5(Bn)(H)4]
