Abstract

Synthesis of [enH2][Mn3(V2O7)2(H2O)2] 1, the first of a new class of organically derivatized mixed metal oxides, is achieved at pH 8 and 140°C by hydrothermal reaction of [Mn3O(OAc)6(py)3][BF4], V2O5, NH2CH2CH2NH2 (en) and H3BO3 in a 0.67: 1: 6: 10 ratio. Crystals of 1 are triclinic P-1, a = 5.743(1) Å, b = 7.931(1) Å, c = 9.313(1) Å, α = 68.54(1), β = 85.78(1), γ= 84.50(1)°, V = 392.62(9) Å3. The X-ray structure refined to R = 0.025. Compound 1 has an anionic open 3-D framework based on linear tri-manganese units of edge shared [Mn((II))O6] octahedra connected through divanadate [V2O7] groups. The organic counterions are located in 1-D tunnels generated from six-membered [Mn2V4] rings. The temperature dependent magnetic susceptibility of 1 indicates a paramagnetic to anti-ferromagnetic transition with a Neel temperature of 10 K.
