Deuterated monoclinic RbD_{2}PO_{4} (DRDP) doped with chromium Cr^{5+} is studied by EPR in 90 K to 400 K temperature range. EPR reveals two types of paramagnetic centers: single Cr^{5+} (S = 1/2) complex and Cr^{5+}-Cr^{5+} coupled pairs with effective spin S = 1. The EPR line splitting of single Cr^{5+} complex in DRDP versus temperature agrees with the unit cell multiplica­tion. The splitting of EPR line of pair spectrum appears at T* = 160 K, far below the phase transition temperatures and is due to the anisotropy of the exchange interaction. The clustering effect in the low-dimensional DRDP is suggested.
