Di-μ-aqua-bis­{diaqua­[μ-4-({4-[bis­(2-hy­droxy­eth­yl)amino]-6-chloro-1,3,5-triazin-2-yl}amino)­benzene­sulfonato]­sodium(I)}

In the dinuclear title compound, [Na(2)(C(13)H(15)ClN(5)O(5)S)(2)(H(2)O)(6)](n), two Na(+) cations, disposed about a centre of inversion, are linked by two bridging water mol­ecules. The coordination geometry is based on an O(5) donor set defined by four water mol­ecules and a 4-amino­benzene­sulfonate O atom in a distorted trigonal–bipyramidal geometry. In the crystal, significant O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds lead to the formation of a three-dimensional architecture.
