STRUCTURAL CHARACTERIZATION OF METALLACROWN COMPLEXES

我们需要束时间来表征金属的结构。 在液晶相和液晶相中，团簇被称为金属冠。 环上与Mn(III)、Fe(III)、V(V)、Cu(II)、Ga(III)的配合物 已经用十种不同的异羟肟酸制备了位置 配基。各种金属，包括Na(I)、Li(I)、K(I)、 锰(II)、镁(II)、铁(III)、镍(II)和铜(II)已被隔离到 金属冠状凹腔。添加的络合物稳定性通过以下方式获得 桥接阴离子，如醋酸盐、硫酸盐、氯化物、溴化物或碘化物 在封装的金属和环形金属之间。我们的具体实验 将在有机和水溶液中建立金属铬化合物 溶液和介晶相，这与金属离子有关 生物系统中的隔离过程。

We request beam time to characterize the structure of metal clusters called metallacrowns in liquid and liquid crystalline phases. Complexes with Mn(III), Fe(III), V(V), Cu(II) and Ga(III) in the ring positions have been prepared using ten different hydroxamic acid ligands. A wide variety of metals including Na(I), Li(I), K(I), Mn(II), Mg(II), Fe(III), Ni(II) and Cu(II) have been sequestered into the metallacrown cavity. Added complex stability is obtained by bridging anions such as acetate, sulfate, chloride, bromide or iodide between the encapsulated and ring metals. Our specific experiments will establish metallacrown composition in organic and aqueous solution and also in mesogenic phases, which are relevant to metal ion sequestering processes in biological systems.
