The synthesis and characterization of Ni₂Zn₁₁-type γ-brasses with composition Mn_2+xZn_11−x (x = 0.06−0.60) are reported. The synthesis follows standard high temperature methods and characterization by single crystal X-ray diffraction (SCXRD) and powder X-ray Diffraction (PXRD) techniques as well as Energy Dispersive Spectroscopy (EDS). First principles electronic structure calculations showed preferential heteroatomic Mn−Zn bonding and repulsive effects of Zn−Zn 3d−3d orbital overlap that influence the metal atom distribution in the structure. Local bonding environments and the relationship of Mn_2+xZn_11-x to other γ-brasses containing 3d metals such as PdCoZn₁₁ and Ni₂Zn₁₁ are discussed.

报道了组成为Mn _{2+ x} Zn _{11- x}（x = 0.06-0.60）的Ni ₂ Zn ₁₁型γ-黄铜的合成与表征。合成遵循标准的高温方法，并通过单晶X射线衍射（SCXRD）和粉末X射线衍射（PXRD）技术以及能量分散光谱（EDS）进行表征。电子结构的第一原理计算表明，优先的杂原子Mn-Zn键合和Zn-Zn 3 d -3 d轨道重叠的排斥效应会影响结构中的金属原子分布。局部键合环境与Mn _{2+ x}的关系讨论了Zn ₁₁ - _x到其他含3d金属的γ-黄铜，如PdCoZn ₁₁和Ni ₂ Zn ₁₁。
