characterized. The molecular structures of all the compounds were studied by single-crystal X-ray crystallography. The strontium and calcium complexes have dimeric configuration with bridging of two alkoxide oxygen atoms between the metals, whereas the barium complex is a trimer. Complexes 4 and 5 show higher volatility and thermal stability with respect to the homoleptic compounds, while barium complex 6 is
使用 1-[2-(二甲氨基)乙基](甲基)氨基}-2-甲基丙-2-醇 (demampH) 和 2,2,6 合成了一类新的钙、锶和钡的杂配复合物,6-四甲基-3,5-庚二酮 (tmhdH)。复合物 [Ca(demamp)(tmhd)}2] (4)、[Sr(demamp)(tmhd)}2] (5) 和 [Ba(demamp)(tmhd)}3] (6) 分别是分两步制备。部分取代的复合物 [Ca(demamp)(btsa)}2] (1), [Sr(demamp)(btsa)}2] (2), 和 [Ba(demamp)(btsa)}2] (3 ) [btsa = 双 (三甲基甲硅烷基) 酰胺] 被分离和表征。通过单晶X射线晶体学研究了所有化合物的分子结构。锶和钙配合物具有二聚体构型,在金属之间桥接两个醇盐氧原子,而钡配合物是三聚体。配合物 4 和 5 相对于均质化合物表现出更高的挥发性和热稳定性,而钡配合物
