The HNBeCO complex is generated the reaction of a beryllium atom with a HNCO molecule in a solid neon matrix, which is identified infrared absorption spectroscopy with isotopic substitutions. The complex is characterized to have a linear structure with a very short Be-N bond distance. Bonding analyses indicate that the complex involves an unprecedented HNBeCO triple bond consisting of two degenerate electron-sharing π bonds and a dative σ bond with the π bonds being much stronger than the σ bond.
HNBeCO络合物是在固体氖基质中由铍原子与HNCO分子反应生成的，通过同位素取代的红外吸收光谱对其进行了鉴定。该络合物的特征是具有线性结构，Be-N键距非常短。键合分析表明，该络合物包含一个前所未有的HNBeCO三键，由两个简并的电子共享π键和一个配位σ键组成，其中π键比σ键强得多。
