The solvothermal reaction of n-BuSn(O)OH with PhPO(3)H(2) afforded the hexanuclear monoorganooxotin phosphonate cage, {[(n-BuSn)(3)(MeO)(3)O](2)(O(3)PPh)(4)}.MeOH 1. When the n-Bu(2)Sn(PhCO(2))(2) precursor reacted with PhPO(3)H(2) in a 1 : 1 stoichiometric ratio, the diorganotin phosphonate ladder [n-Bu(2)SnO(3)PPh](n) 2 was obtained. The reaction of [n-Bu(2)(PrO)Sn](2)O with 4-OH-3-NO(2)-C(6)H(3)AsO(3)H(2) affords the diorganotin arsonate ladder [n-Bu(2)Sn(4-OH-3-NO(2)-C(6)H(3)AsO(3))](n) 3, while the reaction of [n-Bu(2)(PrO)Sn](2)O with 4-NO(2)-C(6)H(4)AsO(3)H(2) and 4-Me-C(6)H(4)SO(3)H gives an diorganotin double chain [n-Bu(2)Sn(4-Me-C(6)H(4)SO(3))(4-NO(2)-C(6)H(4)AsO(3)H)](n) 4, which contains both sulfonate and arsonate ligands. The reaction of 4-NO(2)-C(6)H(4)AsO(3)H(2), EtONa, and Ph(3)SnCl yields a new triorganotin arsonate single chain [(Ph(3)Sn)(4)(4-NO(2)-C(6)H(4)AsO(3))(2).H(2)O](n) 5. The NMR ((1)H, (13)C, (119)Sn) spectra of compounds 1 and 4 were studied.
