摘要

The crystal structures of the proton-transfer compounds of 5-sulfosalicylic acid (3-carboxy-4-hydroxybenzenesulfonic acid) with the aliphatic nitrogen Lewis bases, hydroxylamine, triethylamine, pyrrolidine,morpholine, N-methylmorpholine and piperazine, viz. hydroxyammonium 3-carboxy-4- hydroxybenzenesulfonate (1), triethylaminium 3-carboxy-4-hydroxybenzenesulfonate (2), pyrrolidinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate (3), morpholinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate (4), N-methylmorpholinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate (5) and piperazine-1,4-diium bis(3-carboxy-4-hydroxybenzenesulfonate) hexahydrate (6) have been determined and their comparative structural features and hydrogen-bonding patterns described. Crystals of 4 are triclinic, space group P-1 while the remainder are monoclinic with space group either P21/c (1-3) or P21 (5, 6). Unit cell dimensions and contents are: for 1, a = 5.0156(3), b = 10.5738(6), c = 18.4785(9) ?, β = 96.412(5)°, Z = 4; for 2, a = 8.4998(4), b = 12.3832(6), c = 15.4875(9) ?, β = 102.411(5)°, Z = 4; for 3, a = 6.8755(2), b = 15.5217(4), c = 12.8335(3) ?, β = 92.074(2)°, Z = 4; for 4, a = 6.8397(2), b = 12.9756(5), c = 15.8216(6) ?, α = 90.833(3), β = 95.949(3), γ = 92.505(3)°, Z = 4; for 5, a = 7.0529(3), b = 13.8487(7), c = 15.6448(6) ?, β = 90.190(6)°, Z = 4; for 6, a = 7.0561(2), b = 15.9311(4), c = 12.2102(3) ?, β = 100.858(3)°, Z = 2. The hydrogen bonding generates structures which are either two-dimensional (2 and 5) or three-dimensional (1, 3, 4 and 6). Compound 6 represents the third reported structure of a salt of 5-sulfosalicylic acid having a dicationic piperazine species.
