[Sn (O) (OSiMe ) ] and [{Sn(OSiMe ) } ] have been used to deposit SnO thin films by chemical vapour deposition. Films derived from [Sn (O) (OSiMe ) ] comprise uniform cubes and are highly oriented, whereas those deposited from [{Sn(OSiMe ) } ] are made up of a continuous non-oriented layer with oriented cubes on the surface. The structure of a co-crystal, 2 Sn (O) (OSiMe ) ⋅[Sn(OSiMe ) ] ⋅4 THF, shows that [{Sn(OSiMe ) } ], a liquid at room temperature, adopts a μ-OSiMe -bridged dimeric structure. [Sn (O) (OSiMe ) ] reacts with O in a controlled manner to afford the novel oxo-cluster [Sn O)(OSiMe ) ], the structure of which is reported. In addition, a crystal of {[Sn (O)(OSiMe ) ] [Sn(O)(OSiMe ) Cl] }[Cl] has been fortuitously isolated from the presence of SnCl in the starting material for the preparation of [Sn (O) (OSiMe ) ], and has been shown to incorporate two novel cationic oxo-tin clusters.
[Sn(O)(OSiMe₃)₂]和[{Sn(OSiMe₃)₂}₂]已被用于通过化学气相沉积法沉积SnO薄膜。由[Sn(O)(OSiMe₃)₂]衍生的薄膜由均匀的立方体组成且高度取向，而由[{Sn(OSiMe₃)₂}₂]沉积的薄膜由连续的无取向层组成，其表面有取向的立方体。一种共晶体2Sn(O)(OSiMe₃)₂·[Sn(OSiMe₃)₂]·4THF的结构表明，[{Sn(OSiMe₃)₂}]在室温下为液体，采用μ-OSiMe₃桥连的二聚体结构。[Sn(O)(OSiMe₃)₂]与O以可控方式反应生成新型氧簇[Sn₄O)(OSiMe₃)₆]，并报道了其结构。此外，在制备[Sn(O)(OSiMe₃)₂]的起始原料中因存在SnCl₂而偶然分离出{[Sn₂(O)(OSiMe₃)₃][Sn(O)(OSiMe₃)Cl₂]}[Cl₂]的晶体，且已证明其包含两个新型阳离子氧锡簇。
