title: The 6pi, phosphide-stabilised stannylene dianion [C6H4P2Sn]2-; the first member of a new class of Arduengo-type carbene analogues.
abstract: Dilithiation of 1,2-(PH2)2C6H4 with nBuLi followed by reaction with Sn(NMe2)2 in the presence of the Lewis base donor tmeda [Me2NCH2CH2NMe2] gives [(C6H4P2Sn)(Li.tmeda)2] , containing the phosphide-stabilised, 6pi stannylene dianion [C6H4P2Sn]2-.
