Infrared spectra of Si_nH_4n−1⁺ ions (n = 2–8): inorganic H–(Si–H)_n−1 hydride wires of penta-coordinated Si in 3c–2e and charge-inverted hydrogen bonds

Abstract

SinHm+ cations are important constituents in silane plasmas and astrochemical environments. Protonated disilane (Si2H7+) was shown to have a symmetric three-centre two-electron (3c-2e) Si-H-Si bond that can also be considered...
