摘要：

The reactions of bis(pyrazol-1-yl) acetic acid LCOOH (1) (L = (PZ)(2)CH-) and bis(3,.5-dimethylpyrazol-1-yl)acetic acid L'COOH (2) (L = (3,5-Me(2)Pz)(2)CH-) with organotin oxide (hydroxide) precursors, n-BuSn(O)(OH), n-Bu2SnO, (n-Bu3Sn)(2)O and (Ph3Sn)(2)O has led to the isolation of several organotin compounds containing bispyrazolyl unit(s) on the periphery of the stannoxane structure [n-BuSn(O)O,CL]6 (3), [n-BuSn(O)O2CL'](6) (4), [n-Bu3SnO2CL](n) (5), [n-Bu3SnO2CL'](n) (6), [Ph3SnO2CL](n) (7). [Ph3SnO2CL'](n) (8), [{n-Bu2SnO2CL)(2) (9) and [{n-Bu2SnO2CL'}2O](2) (10). Compounds 5, 7, 9 and 10 have been structurally characterized by X-ray crystallography. In the solid state, these compounds possess interesting 3-D and 2-D supramolecular networks as a result of intermolecular C-H... 0, C-H (...) N, C-H (...) CI and C-H-... pi interactions.
