The condensation reactions of the dimer [ClP(μ-NR)]2 (7) with organic diacids [LL(H)2], possessing linear orientations of their organic groups, result in the formation of phospha(III)zane macrocyles of the type [P(μ-NR)}2(LL)]n of various sizes. The series of macrocycles [P(μ-NtBu)}21,5-(NH)2C10H6}]3 (1), [P(μ-NCy)}2(1,5-O2C10H6)]n [n = 3 (2a); n = 4 (2b)], [P(μ-NtBu)}21,4-(NH)2C6H4}]4 (3), [P(μ-NtBu)}2(1,4-O2C6H4)]3 (4), [P(μ-NCy)}2(1,4-O2C6H4)]3 (5) and [P(μ-NtBu)}2(NH)C6H4OC6H4(NH)}]2 (6) can be related to classical organic frameworks, like calixarenes.
