    Observation of Body‐Centered‐Cubic Cu Nanocluster with Partial Cu(0) Character by Pu Gao, Jing Du, Weijie Hong, Mingzai Wu, Yan Feng, Yanjun Ding, Manzhou Zhu

    Published 2025-02-01
    “…Herein, a Cu(0)‐containing Cu NC is first reported to contain a metallic framework of 23 Cu atoms with a body‐centered‐cubic Cu@Cu8 core, stabilized by 6 triphenylphosphine (TPP) and 18 4‐methylbenzenethiolate ligands, as determined by single‐crystal X‐ray crystallography. The observed structure stands in stark contrast to the FCC and other structures reported for Cu NCs. …”
