Abstract

Niobium and tantalum compounds suitable for use as chemical vapor deposition source reagents, and a process for depositing niobium- or tantalum-containing coatings using the compounds. The compounds have formula EQU M(OR.sup.1).sub.x (R.sup.2 --C(GH)--C--C(G)--R.sup.3).sub.y wherein M is tantalum or niobium; G is oxygen or sulfur; and R.sup.1, R.sup.2, and R.sup.3 are independently selected hydrocarbyl, fluoroalkyl or alkoxy groups,
