N2 - Salts of 5-aminonaphthalene-2-sulfonate with divalent Mg, Mn, Co, and Ni cations have been crystallized and their structures determined by single crystal X-ray methods. The Mg, Mn, and Co salts are isostructural. Crystal data for hexaaquamagnesium(II) 5-aminonaphthalene-2-sulfonate hexahydrate, [Mg(H 2O) 6](H 2NC 10H 6SO 3) 2•6H 2O: monoclinic, P2 1/c, Z=2, a=14.1329(18)Å, b=8.5789(11)Å, c=12.4880(17)Å, β=93.374(3)°, V=1511.5(3)Å 3; hexaaquamanganese(II) 5-aminonaphthalene-2-sulfonate hexahydrate, [Mn(H 2O) 6](H 2NC 10H 6SO 3) 2•6H 2O: monoclinic, P2 1/c, Z=2, a=14.249(3)Å, b=8.5940(17)Å, c=12.505(3)Å, β=93.30(3)°, V=1528.8(6)Å 3; hexaaquacobalt(II) 5-aminonaphthalene-2-sulfonate hexahydrate, [Co(H 2O) 6](H 2NC 10H 6SO 3) 2•6H 2O: monoclinic, P2 1/c, Z=2, a=14.1406(18)Å, b=8.5674(11)Å, c=12.4960(16)Å, β=93.297(2)°, V=1511.4(3)Å 3. The structures are composed of alternating layers of octahedral metal-aqua complexes and sulfonate anions linked by hydrogen bonds. The three water molecules of crystallization are associated with the hexaaquametal cations and sulfonate O atoms. The repeat unit along the a-axis is a single layer. The Ni salt [crystal data for tetraaquabis(5-aminonaphthalene-2-sulfonato-N)nickel(II) dihydrate, [Ni(H 2O) 4(H 2NC 10H 6SO 3) 2]•2H 2O: triclinic, 1, Z=1, a=6.8524(10)Å, b=8.3094(12)Å, c=11.4832(17)Å, α=69.003(2)°, β=76.570(3)°, γ=83.952(2)°, V=593.56(15)Å 3] has a very different structure with direct coordination of the amine N atom to Ni, a modified stacking pattern, and fewer free water molecules. Ag and Ni salts of an amine-substituted naphthalenedisulfonate have also been characterized. Crystal data for diaqua(6-ammonionaphthalene-1,3-disulfonato-O)silver(I) hydrate, [Ag(H 2O) 2(H 3NC 10H 5(SO 3) 2)]•0.42H 2O: monoclinic, P2 1/c, Z=2, a=9.099(3)Å, b=21.406(6)Å, c=7.629(2)Å, β=110.178(4)°, V=1394.9(7)Å 3; tetraaquabis (6-ammonionaphthalene-1,3-disulfonato-O)nickel(II)tetrahydrate, [Ni(H 2O) 4(H 2NC 10H 5 (SO 3) 2) 2]•4H 2O: triclinic, 1, Z=1, a=6.7971(17)Å, b=10.661(3)Å, c=11.165(3)Å, α=68.308(4)°, β=88.292(5)°, γ=84.896(5)°, V=748.8(3)Å 3. The silver salt contains six coordinate metal centers each of which bonds to four sulfonate O atoms from three different anions and two water molecules. The nickel salt contains octahedral cations with four water molecules and two trans sulfonate O atoms. Both structures are layered, but differently from each other and from those of the monofunctional naphthalenesulfonate salts.
