A three‐dimensional network of cadmium

The title complex, poly­bis­N‐(2‐amino­ethyl)‐N‐methyl‐1,2‐ethane­di­amine]­hexa‐μ‐thio­cyanato‐tricadmium(II) monohydrate], Cd₃(NCS)₆(medien)₂]_n·nH₂O medien is N,N‐bis(2‐amino­ethyl)­methyl­amine, C₅H₁₆N₃], adopts a three‐dimensional inorganic polymeric network structure. Two cadmium centres (Cd1 and Cd2) are linked to each other via thio­cyanate bridges. The environment of the Cd1 atom involves only S atoms, making it soft, whereas the environment of the Cd2 atom involves only N atoms, making it hard.
