摘要：

The organic-inorganic hybrid (BEDT-TTF)(3)[Cu-2(mu-C2O4)(3)center dot CH3CH2OH center dot 1.2H(2)O] (I) was obtained using the electrocrystallization method. It comprises a theta(21)-phase organic donor layer and a two-dimensional inorganic antiferromagnetic honeycomb lattice. Cu(II) is octahedrally coordinated by three bisbidenetate oxalates, exhibiting Jahn-Teller distortion. CH3CH2OH and H2O molecules are located within the cavities of the honeycomb lattice. The total formal charge of the three donor molecules was assigned to be +2 based on the bond lengths in the TTF core, which corresponded to the Raman spectra. It is a semiconductor with sigma(rt) = 0.04 S/cm and E-alpha = 40 meV. No long-range ordering was observed above 2 K from zero-field cooling/field cooling magnetization, as confirmed by specific heat measurements. The spin frustration with f > 10 from the antiferromagnetic copper-oxalate-framework was observed. It is a candidate quantum spin liquid.
