Three new, mixed-valent layered vanadyl phosphates, Ag0.43VOPO4·2H2O (AgVPO), Cu0.16VOPO4·2.5H2O(CuVPO), and Zn0.11VOPO4·2.5H2O (ZnVPO), have been synthesized hydrothermally and their structuresdetermined by single-crystal X-ray diffraction: AgVPO is triclinic, space group P
, a = 6.287(1), b = 6.283(1),and c = 13.240(1) Å, 
= 80.98(1), 
= 86.58(1) and 
= 90.00(1)
, Z = 4; CuVPO is triclinic, space group P,a = 6.260(2), b = 6.249(3), and c = 7.257(1) Å, = 83.62(3), = 73.99(2), and = 90.13(4), Z = 2; ZnVPOis triclinic, space group P, a = 6.252(1), b = 6.248(2), and c = 7.339(3) Å, = 83.24(4), = 73.93(2), and = 90.00(2), Z = 2. The structures are related to that of VOPO4·2H2O. Metal powders have been found tobe effective both as reductants and as countercations.
