N2 - A new arsenic-vanadium clusters, [NH 2(CH 2CH 2) 2NH 2] 3[As 8V 14O 42(SO 4)]·6.5H 2O (1), have been hydrothermally synthesized and characterized by IR, elemental analysis, TGA, magnetic property, and single crystal X-ray diffraction analysis. Crystal data: Monoclinic, P2(1)/n, a=21.963(2) Å, b=14.508(1) Å, c=23.054(3) Å, β=118.316(3)°, Z=4. X-ray crystallographic study showed that crystal 1 is composed of the discrete cluster anions [As 8V 14O 42(SO 4)] 6-, organic amine molecules providing charge-compensation, space-filling, and structure-directing roles, and lattice water molecules occupying in the structure. The study of the magnetic susceptibility of 1 demonstrates the presence of antiferromagnetic interaction between V IV cations in 1.
