description

The compounds of formula [MII(H2O)6][CuII(mal)2(H2O)2] [M = Mn (1), Co (2), Ni (3), Cu (4), Zn (5) and H2mal = malonic acid] have been prepared and structurally characterised. Each compound adopts a structure where the layers of [Cu(mal)2(H2O)2]2− anions alternate with layers of [M(H2O)6]2+ cations. The layers are linked to each other through hydrogen bonds affording a three-dimensional network. A quasi-Curie law behaviour is observed for the complexes 1–5 in the temperature range 2.0–298 K.
