摘要：

The platinum carbonyl cluster [Pt12(CO)24]2- dissolved in tetrahydrofuran was transformed into [Pt9(CO)18]2-by laser irradiation (532 nm), as monitored by infrared spectroscopy. Further laser irradiation resulted in the formation of a brown product whose infrared spectrum was different from those of known platinum carbonyl clusters. From observations by scanning tunneling microscopy (STM) and high-resolution transmission electron microscopy (HRTEM), the product is suggested to be a new high-nuclearity platinum carbonyl of size ca. 2.0 nm.
