The first monomeric antimony alkoxides, Sb(OC6H3Me2)(3) (1) and Sb(OEt)(5).NH3 (2), have been crystallographically characterized. The former adopts a trigonal pyramidal geometry, while the latter is octahedral about antimony; hydrogen bonding between NH3 and SbOEt groups in Sb(OEt)(5).NH3 creates a one-dimensional lattice arrangement. Reaction of pyridine with SbCl5 in EtOH/hexane yields the salt [Hpy(+)](9)[Sb2Cl115-][Cl-](4) (3), which has also been crystallographically characterized.
