摘要

标题单晶是在Mg-Al-Zn-Ga合金的合成过程中获得的，这是通过将合金置于高压和高温下实现的。该化合物在空间群Im3 （No. 204）中结晶，具有7个不同的金属原子位置。其中一个是镓，两个是铝和锌，一个是锌和镁，三个是镁。结构模型包含一个以空位为中心的伯格曼簇和一个以镁位点为中心的26面多面体。本研究中的晶体结构框架与之前研究的框架有明显的相似之处，但也有显著的差异[Edagawa et al.(1992)]。费罗斯。[j].地球科学进展[j]。

Magnesium aluminium zinc gallium, Mg_61.81Al_12.77Zn_61.41Ga₂₄.

The title single-crystal was obtained during the synthesis of a Mg-Al-Zn-Ga alloy, which was achieved by subjecting the alloy to elevated pressures and temperatures. The compound crystallizes in the space group Im3 (No. 204), with seven distinct metal-atom sites. One of these is occupied by gallium, two by aluminium and zinc, one by zinc and magnesium, and three by magnesium. The structure model contains a vacancy-centred Bergman cluster and a 26-face polyhedron centred on one of the magnesium sites. The crystal structure framework in this study shows a marked similarity to previously examined frameworks, but also evinces significant differences [Edagawa et al. (1992). Philos. Mag. B 65, 1011-1023].
