Single crystals of the new disodium tricopper(II) tetrakis(hydrogenarsenate(V)) tetrahydrate, Na2Cu3(AsO3OH)4·4H2O were grown under hydrothermal conditions. The compound was characterized by room-temperature single-crystal X-ray diffraction, SEM-EDS analysis, Raman spectroscopy and magnetic susceptibility measurements. Na2Cu3(AsO3OH)4·4H2O represents a new layered structure-type [space group P21/c, a = 8.7089(17), b = 9.7452(19), c = 9.3353(19) Å, β = 92.63(3)°, V = 791.4(3) Å3, Z = 4]. The layers are normal to [100] and are composed of the isolated Cu3O12 units interconnected by AsO3OH coordination tetrahedra. The crystal structure of Na2Cu3(AsO3OH)4·4H2O is related to a group of compounds formed by Cu2+–(XO4)3- layers (X = P5+, As5+) linked by M cations (M = alkali, alkaline earth, Pb2+, or Ag+) and partly by hydrogen bonds, where distinct links and patterns of the Cu3O12 units and XO4 tetrahedra were observed. The magnetic susceptibility and magnetization measurements reveal a canted antiferromagnetic ground state which is in excellent agreement with a layered magnetic structure determined by the copper ions of the Cu3O12 units.
