✦ Synopsis

The reaction of the coordinatively unsaturated mono-tungsten center W(CO) s with NO was investigated by time-resolved infrared absorption spectroscopy in the wavenumber region 1650-2035 cm-~ in the gas phase at room temperature. Initially, W(CO) 5 reacted with NO to make a nitrosyl coordination compound W(CO)x(NO) where x is probably 4 or 5. The coordinated nitrosyl and carbonyl stretching frequencies were found to be around 1726 and 1999 cm -~, respectively. W(CO)~(NO) reacted successively with NO to form a relatively stable complex W(CO)3(NO) 2 with one CO stretching band at 2015 cm -1 and two NO stretching bands at 1676 and 1712 cm -1.
