Patent ID: 8399695

Claim:
An organometallic precursor compound represented by the formula (H) m M(R) n wherein M is a metal or metalloid, R is the same or different and is selected from (i) a substituted, saturated heterocyclic radical containing at least one nitrogen atom selected from aziridinyl, azetidinyl, pyrrolidinyl, thiazolidinyl and piperidinyl, and (ii) a substituted or unsubstituted, unsaturated heterocyclic radical containing at least one nitrogen atom selected from pyrrolyl, pyridinyl, pyrimidinyl, pyrrolinyl, pyrazoplyl, thiazolyl, oxazolyl, imidazolyl, imidazolidinonyl, imidazolidinethionyl, quinolinyl, isoquinolinyl, carbazolyl, triazolyl, indolyl and purinyl, m is from 0 to a value less than the oxidation state of M, n is from 1 to a value equal to the oxidation state of M, and m+n is a value equal to the oxidation state of M.
