The double salt tris(diisopropylammonium) tetrachloridoferrate(III) dichloride: Synthesis, crystal structure, and vibrational spectra

Tris(diisopropylammonium)tetrachloridoferrate(III) dichloride crystallizes in the monoclinic space group P2₁/c (a = 7.6685(2) ?, b = 17.6079(3) ?, c = 23.3217(4) ?, β = 91.396(2)°, V = 3148.1(1) ?³, Z = 4, T = 113 K) with three diisopropylammonium cations (dip), one tetrachloridoferrate(III) anion, and two chloride anions in the asymmetric unit. The dip cations and the chloride anions form hydrogen bonded one-dimensional polymers along [010]. The tetrachloridoferrate(III) anion, habituated in between these chains, is not involved in any hydrogen bonding. The structural characterization is supported by infrared and Raman spectroscopic data.
