title: New vanadium phosphate ([(phen)VIVO]2(VV2O5)(HPO4))n with chiral layer architecture.
abstract: A new layered vanadium phosphate ([(phen)V(IV)O](2)(V(V)(2)O(5))(HPO(4))n has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, and single-crystal X-ray diffraction. This compound crystallized in the monoclinic space group P2/c with a = 9.979(2) A, b = 9.886(2) A, c = 15.298(3) A, beta = 102.86(3) degrees, V = 1471.3(5) A(3), and Z = 4. In the structure of this compound, two nitrogen atoms of 1,10-phen are directly coordinated to the vanadium skeleton. Interestingly, the crystal structure consists of two types of chiral layers, one left-handed and the other right-handed, which lead to a racemic solid-state compound. In each layer, there coexist three distinct rings, described as a 8-membered ring [V(2)(oct)P(2)O(4)], 12-membered ring [V(2)(omicron)(ct)V(2)(tet)P(2)O(6)], and 16-membered ring [V(2)(omicron)(ct)V(4)(tet)P(2)O(8)].
