In the solid state dimethylsulfoximide (1) (orthorhombic; space group
Pbca; a=577.8, b=931.2 and c=1645.6 pm) makes intermolecular N-H ... N
hydrogen bonds. The hydrogen halide salts (CH3)(2)S(O)NH(2)(+)Hal(-)
((2), Hal(-)=Cl-; (4), Hal(-)=Br-) reacts with metal halides to yield
(CH3)(2)S(O)NH(2)(+)MHal(y)(n-) with the complex anions ((5), MHal(y)(
n-)=SbCl4-; (6), MHal(y)(n-)=SbCl52-; (7), MHal(y)(n-)=SbCl6-; (8), MH
al(y)(n-)=SbBr52-; (9), MHal(y)(n-)=AlCl4-), 2 crystallizes from ethan
ol (96%) as [(CH3)(2)S(O)NH2+Cl-](2) . H2O (3). The structures of 3 (m
onoclinic; space group P2(1)/c; a=917.0, b=1344.7, c=1080.8 pm and bet
a=103.8 degrees; Z=10), 4 (orthorhombic; space group Pbcn; a=1028.9, b
=1132.6, c=1074.1 pm; Z=8) and 6 (monoclinic; space group C2/c; a=2041
.1, b=1101.4, c=3365.6 pm and beta=153.8 degrees; Z=8) are determined
by X-ray analysis. In 6 Sb is coordinated in a distorted octahedra by
6 CI in three short (mean 245,5 pm; SbCl3) and three long distances (2
91 to 299 pm; Cl-). Two of the chloride ions connect the Sb atoms to i
nfinite Sb . Cl . Sb chains. Except for 7 and 9 there are bridges betw
een the NH2 groups and the halide ions. The NH valence vibrations are
discussed in view of hydrogen bonding.
