The following nine unsymmetrically axially substituted antimony(V) tetraphenylporphyrins with an antimony-carbon bond or an antimony-fluorine bond were synthesized: [(TPP)Sb(Me)(OEt)]+ClO4- (1-ClO4), [(TPP)Sb(Me)(OC6H4CH3-p)]+ClO4- (2-ClO4), [(TPP)Sb(Me)(SC6H4CH3- p)]+ClO4- (3-ClO4), [(TPP)Sb(Me)(NHC6H4CH3-p)]+ClO4- (4-ClO4), [(TPP)Sb(Me)(NHCH2C6H5)]+ClO4- (5-ClO4), [(TPP)Sb(Me)(OC(=O)C6H4Cl- m)]+PF6- (6-PF6), [(TPP)Sb(Me)(Et)]+PF6- (7-PF6), [(TPP)Sb(Me)(CH2CHMe2)]+PF6- (8-PF6), and [(TPP)Sb(F)(OH)]+ClO4- (9- ClO4). All nine compounds were stable towards atmospheric moisture. X-Ray crystallographic analysis of 6-PF6 revealed that the antimony atom lies at 0.182 A out-of-plane of the four nitrogens (Δ4N) toward the carbon atom; 6- PF6: space group P21/n, a = 25.49(2), b = 11.27(1), c = 16.58(1) A, β = 96.74(5)°, R = 0.064.
