The crystal and molecular structures of 1-naphthylphenyliodonium tetrafluoroborate and 1-naphthylphenyliodonium tetrakis(pentafluorophenyl)gallate

Abstract

The X-ray structures of 1-naphthylphenyliodonium tetrafluoroborate 1 and 1-naphthylphenyliodonium tetrakis(pentafluorophenyl)gallate 2 are reported. Crystals of 1 are monoclinic, space group P2(1)/c, with unit cell dimensions a = 11.8914(11), b = 8.8699(9), c = 14.4445 (13) Å, β = 90.944(4)°, Z = 4, and R = 0.0596 for 8286 unique observed reflections. Crystals of 2 are monoclinic, space group P2(1)/c, with unit cell dimensions a = 15.003(5), b = 18.287(6), c = 14.738(6) Å, β = 115.436(13)°, Z = 4, and R = 0.0222 for 8063 unique observed reflections. The iodonium cations of 1 exist as π-stacked dimers; however, those of 2 are monomeric.
