Abstract
The present invention relates to a raw material for chemical deposition shown in a formulae below and including an organoplatinum compound in which diimine containing two imines and an alkyl anion are coordinated to divalent platinum. In the formulae, each of substituents Rto Ron the diimine represents a hydrogen atom, an alkyl group or the like and has a carbon number of 5 or less. Each of alkyl anions Rand Ris an alkyl group having a carbon number of 1 or more and 3 or less. The raw material has high vapor pressure and low decomposition temperature, and thus it is possible to manufacture a platinum thin film at low temperature.
