Cluster transformation of [Cu3(μ3-H)(μ3-BH4)((PPh2)2NH)3](BF4) to [Cu3(μ3-H)(μ2,μ1-S2CH)((PPh2)2NH)3](BF4) via reaction with CS2. X-ray structural characterisation and reactivity of cationic clusters explored by multistage mass spectrometry and computational studies

[Cu₃(μ₃-H)(μ₃-BH₄)((PPh₂)₂NH)₃](BF₄) reacts with CS₂ to produce [Cu₃(μ₃-H)(μ₂,μ₁-S₂CH)((PPh₂)₂NH)₃](BF₄), whose cation loses CH₂S upon ligand loss.
