资源简介:

The cyclic Ge­(I) compound [(ADCPh)­Ge]2 (4) (ADCPh = {CN­(Dipp)}2CPh, Dipp = 2,6-iPr2C6H3) containing a 6π-electron C4Ge2 framework has been isolated as a red crystalline solid. CASSCF calculations reveal a closed-shell singlet ground state for 4 with a considerable diradical character (y = 34%). Thus, the diradicaloid 4 readily splits dihydrogen at room temperature to yield the elusive bis-hydrido­germylene [(ADCPh)­GeH]2 (5).
