摘要：

[(thf)3Na{(pz)3Ge}] 1 and [(thf)2(pzH)Na{(PZ)3Sn}]2 2 (pz = pyrazol-1-yl) are obtained by the reaction of pzNa with GeCl2-dioxane and SnCl2, respectively, in a 3:1 molar ratio in thf (thf = tetrahydrofuran); the X-ray structure determination shows that the [(PZ)3Ge]- unit in 1 is a tridentate ligand to the sodium, while the [(PZ)3Sn]- unit in 2 is only bidentate resulting in dimerisation to produce overall a twelve-membered ring system.
