5-(Dimethyl­ammonio)naphthalene-1-sulfonate dihydrate

There are two formula units in the asymmetric unit of the title compound, C12H13NO3S·2H2O. In the crystal structure, mol­ecules are linked by inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds, forming a three-dimensional network

[N,N,N′,N′-Tetra­kis(benzimidazol-2-yl­meth­yl)ethane-1,2-diamine]copper(II) sulfate monohydrate

In the title compound, [Cu(C34H32N10)]SO4·H2O, the CuII ion is coordinated by six N atoms of a hexa­dentate N,N,N′,N′-tetra­kis(benzimidazol-2-ylmeth­yl)ethane-1,2-diamine (EDTB) ligand, in a distorted octa­hedral environment. In the crystal structure, inter­molecular N—H⋯O and weak C—H⋯O hydrogen bonds connect the cations, anions and water mol­ecules into a three-dimensional network. The O atoms of the anion are disordered over two sites with refined occupancies of 0.711 (2) and 0.289 (2)
