HNBeCO络合物是通过铍原子与HNCO分子在固体氖基质中的反应产生的，其通过具有同位素取代的红外吸收光谱法鉴定。配合物的特征在于具有线性结构，具有非常短的Be-N键距。成键分析表明，配合物中存在一个前所未有的HNBeCO三键，该三键由两个简并的共电子π键和一个配位的σ键组成，π键比σ键强得多.
The HNBeCO complex is generated via the reaction of a beryllium atom with a HNCO molecule in a solid neon matrix, which is identified via 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.
