Mr= 665-74, triclinic, P), a = 16.428 (5), b=12.122(4), c=6.954(1)A, ct=97.61(2), fl= 77-36 (2), y=110.09(2) ° , V=1266.52A 3, Z=2, Dm(flotation ) = 1.72, D~= 1.74 g cm -3, /~(Mo Ka) = 6.3cm -1, 2=0.71069A, F(000)=676, T=294K, final R = 0.054 for 4724 reflections with F o > 3a(Fo). The structure consists of one Na ÷ and two independent K + cations, three independent C7HaNO3S - anions and one H20 molecule, in a polymeric framework. The anions are bonded to the cations through the N as well as the carbonyl and sulphonyl O atoms. The H20 molecule forms bridges between two Na + and between one Na ÷ and one K ÷ ion, and is also involved in H bonds with the carbonyl groups of two CvH4NO3S- anions.
