Decarbonylation of a cyclic bis‐phosphaethynolatostannylene [(ADC)Sn(PCO)]₂based on an anionic dicarbene framework (ADC = PhC{N(Dipp)C}₂; Dipp = 2,6‐iPr₂C₆H₃) under UV light results in the formation of a Sn₂P₂cluster compound [(ADC)SnP]₂as a green crystalline solid. The electronic structure of [(ADC)SnP]₂is analyzed by quantum‐chemical calculations. At room temperature, [(ADC)SnP]₂reversibly binds with CO₂and forms [(ADC)₂{SnOC(O)P}SnP]. [(ADC)SnP]₂enables catalytic hydroboration of CO₂and reacts with elemental selenium and Fe₂(CO)₉to afford [(ADC)₂{Sn(Se)P₂}SnSe] and [(ADC)Sn{Fe(CO)₄}P]₂, respectively. All compounds are characterized by multinuclear NMR spectroscopy and their solid‐state molecular structures are determined by single‐crystal X‐ray diffraction.
