The complex adducts of silver(I) p-toluenesulfonate, [Ag(pts)], with t
he nitrogen bases pyridine (1:1), [{Ag(pts)}(py)](n) (2), 2-aminopyrid
ine (2:4), [{Ag(pts)}(2)(2-apy)(4)] (3), 2-aminopyrimidine (1:1), [{Ag
(pts)}(2-ap)](n) (4), 4,6-dimethyl-2-aminopyrimidine (2:3), [{Ag(pts)}
(2)(dmap)(3)](n) (5), and 3-aminobenzoic acid (2:4), [{Ag(pts)}(2)(3-a
ba)(4)] (6), have been prepared and their structures, together with th
at of the parent compound, silver(I) p-toluenesulfonate (1), determine
d by X-ray diffraction. Crystals of 1 (C14H14Ag2O6S2) are monoclinic,
space group P2(1)/a, Z = 2, with a = 8.596(3) Angstrom, b = 6.0330(4)
Angstrom, c = 15.363(4) Angstrom, and beta = 93.03(1)degrees. The poly
meric structure is based on bis(sulfonato-(O,O') bridged dimers analog
ous to those found in some of the O,O'-bridged silver(I) carboxylates,
these also having pseudo trigonal bipyramidal AgO4 centers. All sulfo
nate oxygens are utilized in coordination. The structures of the monoh
eteroaromatic nitrogen donor group adducts (2, 3, and 6) are either po
lymeric [2 (C12H12AgNO3S): AgN2O2 centers] or discretely dimeric [3 (C
34H38Ag2N8O6S2) and 6 (C42H42Ag2N4O14S2): both AgN2O2] and can be cons
idered the result of replacement of either one or two oxygen sites abo
ut the silver in [Ag(pts)] by nitrogen donors, with subsequent rearran
gement about very distorted tetrahedral silver centers. For 2, crystal
s are monoclinic, space group P2(1), Z = 2, with a = 9.1237(8) Angstro
m, b = 5.553(1) Angstrom, c = 12.439(1) Angstrom, and beta = 91.182(8)
degrees For 3, crystals are triclinic, space group P (1) over bar, Z =
1, with a 8.635(3) Angstrom, b = 10.434(3) Angstrom, c = 11.138(3) An
gstrom, alpha = 104.89(2), and beta = 90.20(2)degrees, gamma = 99.94(2
)degrees. For 6, crystals are monoclinic, space group P2(1)/a, Z = 4,
with a = 8.006(2) Angstrom, b = 31.675(8) Angstrom, c = 8.803(2) Angst
rom, and beta = 104.413(9)degrees. Hydrogen-bonding interactions via t
he second functional group in both 3 and 6 give additional lattice sta
bility. However, with the bifunctional heteroaromatic pyrimidines, ext
ension of the polymer structures occurs through both ring nitrogens to
give either a simple ribbon polymer (4, C11H12AgN3O3S) (trigonal plan
ar AgON2 repeat) or a pyrimidine-linked, sulfonate-bridged eight-membe
red cyclic dimer unit, in which the tetrahedral Ag2O2N2 centers incorp
orate an additional unidentate pyrimidine (5, C32H41Ag2N9O6S2) For 4,
crystals are monoclinic, space group P2(1)/n, Z = 4, with a = 6.535(2)
Angstrom, b 7.3440(8) Angstrom, c = 26.13(1) Angstrom, and beta = 90.
44(1)degrees: For 5, crystals are monoclinic, space group C2/c, Z = 4,
with a = 21.312(6) Angstrom, b = 10.650(1) Angstrom, c = 17.565(5) An
gstrom, and beta = 110.58(1)degrees. Hydrogen bonding is also signific
ant in lattice stabilization in both of these structures. The preparat
ion of an unstable adduct of Ag(pts) with aniline, [{Ag(pts)}(an)(3)]
7, is also reported, and infrared spectroscopy indicates that it is ha
s both amine-bonded aniline as well as uncoordinated aniline.
