N2 - A new lithium copper diselenite chloride hydrate, Li2Se2O5(H2O)1.5·CuCl2, was prepared from aqueoussolution. Its unique 2D structure can be interpreted as Li2Se2O5(H2O)1.5 layers with CuCl2 hosts embeddedin the interlayer space, and be considered halfway between the salt-inclusion and host–guest structures.The CuO2Cl4 octahedra form chains similar to those in CuCl2·2H2O, yet water molecules are coordinatedexclusively to Li+ while Se2O52− and Cl− bridge Li+ and Cu2+. The complexity of the structure is likelyresponsible for both very long pre-crystallization time and non-existence of the corresponding bromideanalogue. Despite the relatively long Cu⋯Cu separations, the compound exhibits weak ferromagneticinteractions along the chains of CuO2Cl4 octahedra.
