Sterically hindered imidazole ligands are described, along with their synthesis, which are capable of coordinating to Group 2 metals, such as: calcium, magnesium, strontium, in an eta-5 coordination mode which permits the formation of monomeric or dimeric volatile complexes.
A compound comprising one or more polysubstituted imidazolate anions coordinated to a metal selected from the group consisting of barium, strontium, magnesium, radium or calcium or mixtures thereof. Alternatively, one anion can be substituted with and a second non-imidazolate anion.
Synthesis of the novel compounds and their use to form BST films is also contemplated
具有立体位阻的
咪唑配体被描述,以及它们的合成,这些
配体能够与2族
金属(如:
钙、
镁、
锶)配位形成η-5配位模式,从而形成单聚或二聚挥发性络合物。
一种化合物包括一个或多个多取代
咪唑酸根离子与从
钡、
锶、
镁、
镭、
钙或其混合物中选择的
金属配位。或者,一个阴离子可以被取代为第二个非
