The reactions of tin(II) chloride with phosphonic and phosphinic acids under hydrothermalconditions result in structures with varying dimensionalities. The synthesis and characterization of eight new structures is described. SnCl(HPhPO2), I, triclinic, P
(No. 2), has latticeparameters a = 5.4767(6) Å, b = 8.8106(9) Å, c = 9.5219(10) Å, 
= 104.564(2)

= 99.349(2), and V = 434.34(8) Å3. (SnCl)2MePO3, II, triclinic, P (No. 2), has a =4.7275(17) Å, b = 6.152(2) Å, c = 13.632(5) Å, = 81.299(7), = 89.052(7), = 89.781(7),and V = 391.8(3) Å3. Sn2Cl(EtPO3)EtPO2OH, III, monoclinic, P21/m (No. 11), has a = 4.814(4) Å, b = 8.530(4) Å, c = 15.214(8) Å, = 99.09(10), and V = 616.9(7) Å3. -SnEtPO3, IV,monoclinic, Cc (No. 9), has a = 4.6415(13) Å, b = 18.695(5) Å, c = 6.4964(18) Å, = 99.907(4), and V = 555.3(3) Å3.

For the first time, a three-ring (3R) phosphonatechain and an open-chain (i.e., no rings) phosphinate "wire" have been isolated. The phosphateanalogues of these structures serve as key structural motifs in tin(II), zinc(II), and cobalt(II) phosphates, underscoring their role in the formation of framework phosphates. Wepropose that metal phosphate wires could play an important role in the formation of open-framework materials.
