Description We have measured the magnetic susceptibility (X) and heat capacity (C(p)) of beta-Cu(2-x)Zn(x)V(2)O(7) (x = 0, 0.05, 0.1, 0.15, 0.2, 0.3, 2) in the temperature range 2-300 K. A one-dimensional alternating exchange Heisenberg antiferromagnetism (HAF) is observed in all compositions with chains of infinite length. The intra-chain exchange remains uniform and decreases marginally with dilution of the magnetic state. A cooperative ordering is seen in the magnetic chains for all Zn concentrations (x
