N2 - The laser-induced polymerization of powdered SiI4 has been investigated by time-of-flight (TOF) mass spectroscopy combined with density functional theory (DFT) calculations. In the positive ion spectra, three series of abundant clusters (Sin I2 n + 1+ (n = 1-6), Sin I4 n / 3 + 3+ (n = 7-15), Sin I3 n / 2 - 7+ (n = 16-22)) were observed. DFT calculations have revealed that the abundant clusters are straight chains with iodine bridge in n = 1-6, multi-cyclic rings of pentagons in n = 7-15, and cages constructed by pentagons and hexagons in n = 16-22. A silicon-rich six-membered ring, i.e., an unsaturated ring like benzene, was detected in less abundant clusters.
