corner-sharing Mo2F2O5} cores, in which two octahedral Mo ions are linked by one oxygen atom (Mo-O 1.90–1.92 A) and two triazolyl groups (Mo-N 2.37–2.40 A). The latter occupy the cis-positions in the Mo2F2O5(tr)2} coordination clusters (“secondary building blocks”). Terminal fluoride and two “molybdenyl” oxygen atoms complete the coordination sphere of each molybdenum ions. In both cases the ligands show
摘要 新的钼 (VI) 氟氧化物 - 有机杂化物,[Mo2F2O5(tr2ad)] (1) 和 [Mo2F2O5(tr2ad2)] (2),由角形或线性 N1,N2-(1,2,4-triazol-4 -yl) 桥(tr2ad, 1,3-bis(1,2,4-triazol-4-yl)adamantane; tr2ad2, 3,3'-bis(1,2,4-triazol-4-yl)-1 ,1'-双金刚烷),在水热条件下在 HF 水溶液中制备。该化合物的结构包括双核共角 Mo2F2O5} 核,其中两个八面体 Mo 离子通过一个氧原子 (Mo-O 1.90–1.92 A) 和两个三唑基 (Mo-N 2.37–2.40 A) 连接。后者占据 Mo2F2O5(tr)2} 配位簇(“次要构件”)中的顺式位置。末端氟化物和两个“钼基”氧原子构成了每个钼离子的配位球。
