Abstract Monomeric three‐coordinate (amidinato)tin chloride [PhC(N t Bu) 2 SnCl] ( 1 ) was prepared by the reaction of N , N′ ‐di‐ tert ‐butylcarbodiimide, phenyllithium and SnCl 2 . Themetathesis reaction of 1 with AgSO 3 CF 3 and (Me 3 Si) 2 NLi afforded the formation of PhC(N t Bu) 2 SnOTf (Tf = CF 3 SO 2 ) ( 2 ) and PhC(N t Bu) 2 SnN(SiMe 3 ) 2 ( 3 ). The reductive dehalogenation of 1 with L‐selectride resulted in the formation of the four‐coordinate homoleptic tin compound Ph 2 C 2 (N t Bu) 4 Sn ( 4 ). Compounds 1 , 2 , 3 , and 4 were characterized by single‐crystal structural analysis. Furthermore, 1 was treated with Fe 2 (CO) 9 to afford the Lewis acid–base adduct 5 .
