ABSTRACT:
This invention relates to organometallic compounds represented by the formula (L1)xM(L2)ywherein M is a metal or metalloid, L1and L2are different and are each a hydrocarbon group or a heteroatom-containing group;xis a value of at least 1;yis a value of at least 1;x+yis equal to the oxidation state of M; and wherein (i) L1has a steric bulk sufficiently large such that, due to steric hinderance,xcannot be a value equal to the oxidation state of M, (ii) L2has a steric bulk sufficiently small such that, due to lack of steric hinderance,ycan be a value equal to the oxidation state of M only in the event thatxis not a value of at least 1, and (iii) L1and L2have a steric bulk sufficient to maintain a heteroleptic structure in whichx+yis equal to the oxidation state of M; a process for producing the organometallic compounds, and a method for producing a film or coating from organometallic precursor compounds.
