Zhang, Zongchao published the artcileFTIR study of novel palladium trimethylphosphine carbonyl clusters encaged in zeolite Y, HPLC of Formula: 6972-05-0, the publication is Polyhedron (1991), 10(7), 673-81, database is CAplus.
Green Pd(Me3P)(CO)2 (TMPC) clusters in zeolite Y were prepared using a ship-in-a-bottle method. Me3P (TMP) ligands stabilize Pd clusters of small nuclearity; they preferentially coordinate to the corner Pd atoms. Absorption bands of triply-bonded CO (1886 cm-1) are observed only for samples with initially large Pd nuclearity (x > 4). Bands at 1960 and 1950 cm-1, attributed to doubly-bonded CO in a butterfly configuration, dominate the IR spectra. The Pd core in Pd TMPC clusters is electron-rich, in comparison to Pd single crystals, due to electron donation from phosphorus to the Pd. The spectra of the zeolite encaged clusters differ from those reported for PdR3P (R = alkyl) such as Et and Bu) clusters in solution with nuclearity varying 4-38. Zeolite encaged Pd TMPC clusters are stable at 200¡ã in a flow of H2 + CO. At 300¡ã, the TMP ligands decompose and poison the Pd particles.
