Phosphine + methanal
WebA metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R 3 P (R = alkyl, aryl). Metal phosphine complexes are useful in homogeneous catalysis. WebPhosphine (PH₃) is a colorless, flammable, and explosive gas at room temperature that smells like garlic or decaying fish. Exposure to phosphine may cause, nausea, vomiting, stomach pain, diarrhea, thirst, muscle pain, difficulty breathing, and fluid in the lungs. Higher exposures and long-term exposure may cause serious harm.
