Abstract

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. Crystallographic data: 1, C24H27O3Sb, a = 10.9080(2), b = 11.9660(2), c = 17-7260(4) Angstrom, alpha = 109.740(1)degrees, monoclinic P2(1)/c (unique axis a), Z = 4; 2, C10H28NO5Sb, a = 7.7220(l), b = 19.0700(2), c = 21.6800(3) Angstrom, 93.4960(7)degrees, monoclinic P2(1)/c, Z = 8; 3, C45H54Cl15N9Sb2, a 13.4300(2), b = 14.4180(2), c = 17.4180(3) Angstrom, alpha = 82.7650(7), beta = 77.5570(7), gamma = 70.7670(7)degrees, triclinic Z = 2.
