Structures of tetraaquabis(hydroxymethanesulfonato)magnesium(II) and hexaaquaaluminium(III) hydroxymethanesulfonate

Structures of dimethylammonium metal(III) sulfate hexahydrates (metal = Al, Cr)

“…The Cr and A1 atoms positioned on the symmetry centres are octahedrally coordinated by the Ow atoms of the water molecules. The weighted means of A1--Ow and Cr--Ow bond lengths [1.880 (6) and 1.960 (4) A, respectively] are in accord with the corresponding averaged bonds from related literature data: 1.875 (Schein, Lingafelter & Stewart, 1967), 1.87 (Lipson, 1935), 1.86 (at 170 K;Fletcher & Steeple, 1964), 1.868 (2) (neutron data; , 1.851 (5) and 1.897 (2) (neutron data; Abdeen, Will, Sch/ifer et al, 1981) and 1.89/~ (Cameron, Chute, Owen, Aherne & Linden, 1990) for the A1--Ow bonds and 1.954 (Schein et al, 1967) and1.962 A (Chesick &Doany, 1981) for the Cr--Ow bonds. The mean deviations from 90 ° of Ow---A1--Ow and Ow---Cr--Ow bond angles are 2.2 (2) and 2.5 (4) ° , respectively.…”

The dimer bis(μ-8-hydroxy-7-iodoquinoline-5-sulfonato-κ3N,O:O′)bis[triaquamagnesium(II)] tetrahydrate

“…The coordination of the Mg 2+ ion is distorted octahedral, consisting of N (N1) and O (O4) atoms of the oxine ring, one of the O (O3 i ) (symmetry code as in Table 1) atoms of a sulfonate group and three water molecules ( Fig. The bond distances and angles (Table 1) in this complex agree with those in related sulfonate complexes (Cai et al, 2001;Cameron et al, 1990;Francis et al, 2003b). The bond distances and angles (Table 1) in this complex agree with those in related sulfonate complexes (Cai et al, 2001;Cameron et al, 1990;Francis et al, 2003b).…”

“…In the crystal structure of tetraaquabis(hydroxymethanesulfonato)magnesium(II), the sulfonate group and water molecules are involved in coordination (Cameron et al, 1990), whereas in the three other crystal structures, namely hexaaquamagnesiumbis(8-anilino-1-naphthalenesulfonate) hexahydrate (Cody & Hazel, 1977), hexaaqua(1,5-napthalenedisulfonato)magnesium (Cai et al, 2001) and the magnesium salt of 7-hydroxy-8-(phenylazo)-1,3-naphthalenedisulfonic acid (Ojala et al, 1994), the sulfonate groups are not involved in coordination and the metal atoms are surrounded only by water molecules. In the crystal structure of tetraaquabis(hydroxymethanesulfonato)magnesium(II), the sulfonate group and water molecules are involved in coordination (Cameron et al, 1990), whereas in the three other crystal structures, namely hexaaquamagnesiumbis(8-anilino-1-naphthalenesulfonate) hexahydrate (Cody & Hazel, 1977), hexaaqua(1,5-napthalenedisulfonato)magnesium (Cai et al, 2001) and the magnesium salt of 7-hydroxy-8-(phenylazo)-1,3-naphthalenedisulfonic acid (Ojala et al, 1994), the sulfonate groups are not involved in coordination and the metal atoms are surrounded only by water molecules.…”
