The crystal structure of a new pyrazine‐bridged trimer of oxo‐centered triruthenium–carbonyl clusters formulated as [Ru₃O(EtCOO)₆(CO)(pyrazine)]₂[Ru₃O(EtCOO)₆(CO)(μ‐pyrazine)₂] (1) has been unequivocally determined by single‐crystal X‐ray diffraction (SC‐XRD) analysis at 100 K. A supramolecular cyclic assembly of two trimers was formed via intermolecular CO⋯CO contacts, which is further assembled into a three‐dimensional orthogonal layer‐by‐layer stack via hydrogen bonds.

吡嗪桥联的三聚氧羰基中心的三聚体和由多个非共价接触构成的超分子组装体

新型以吡嗪桥联的以氧为中心的三钌-羰基簇的三聚体的晶体结构，公式为[Ru ₃ O（EtCOO）₆（CO）（吡嗪）] ₂ [Ru ₃ O（EtCOO）₆（CO）（μ-吡嗪）₂ ]（1）已通过100 K单晶X射线衍射（SC-XRD）分析明确确定。两个三聚体的超分子环状组装体通过分子间CO⋯CO接触形成，并进一步组装成通过氢键的三维正交逐层堆叠。
