A conventional solution‐based route to a cyclic trimeric organozinc compound [{Zn(Et)( β ‐diketonate)} 3 ] ( β ‐diketonate=OC(OMe)CHC(Me)O, 1 ) is described, with 1 structurally characterized for the first time. The ligand selection of bidentate β ‐diketonates is shown to be key to isolating a cyclic trimer. Additional reaction of β ‐diketonates with diethyl zinc were spectroscopically characterized as compounds of the type [{Zn(Et)( β ‐diketonate)} n ] ( β ‐diketonate=OC(Me)CHC(Me)O, 2 , OC(O t Bu)CHC(Me)O, 3 ). Further studies have shown that selective oxidation of these species produces cubanes of the general formula [{Zn(OC(R)CHC(Me)O) 2 Zn(Et)OEt} 2 ] (R=OMe, 4 ; Me, 5 ; O t Bu, 6 ), allowing a high oxygen content whilst remaining structurally suitable for use as precursors. The successful deposition of thin films of zinc oxide through aerosol‐assisted chemical vapor deposition (AACVD), using a novel precursor, is described and fully characterized.
