5-Me2pzH · 4H2O complex (6) was obtained as a by-product in the synthesis of complex 4. The reaction of [ReNCl2(PPh3)2] with Me2pzH was accompanied by hydrolytic denitration giving rise to the mixed-ligand complex [Re2O3Cl2(μ-3,5-Me2pz)2(3,5-Me2pzH)(PPh3)] (7). The reaction of (NH4)2[ReBr6] with a Me2pzH melt gave the trans-[ReBr4(3,5-Me2pzH)2] · · Me2CO complex (8). The structures of complexes 2 and 4–8 were
合成了具有 3,5-二甲基吡唑 (Me2pzH) 的单核和双核 ReIV 和 ReV 复合物。顺式-[Re2O3Cl4(3,5-Me2pzH)4] 复合物 (cis-1) 是通过 NH4ReO4 与 K[HB(Me2pz)3] 在浓盐酸中反应或通过回流 [ReCl3(MeCN)(PPh3 )2] 与空气中的 Me2pzH。通过将干燥的 HBr 通过 [Re2O3Br2(μ-3,5-Me2pz)2(3,5-Me2pzH) 溶液合成溴化物配合物 trans-[Re2O3Br4(3,5-Me2pzH)4] (trans-2) 2] (4) 在氯仿中。由 (Et4N)2[ReOCl5] 或 Cs2[ReOCl5] 和 Me2pzH 制备吡唑酯桥络合物 [Re2O3Cl2(μ-3,5-Me2pz)2(3,5-Me2pzH)2] (3)。相应的溴化物和碘化物配合物[Re2O3X2(3,5-Me2pz)2(3
