The influence of boron atoms on the magnetic properties of Νd(Co_{1-x}B_{x})_{5} (i.e. ΝdCo_{5}, NdCo_{4}B, Νd_{3}Co_{11}Β_{4} and Νd_{2}Co_{7}Β_{3}) compounds has been studied. These structures are based on the well-known CaCu_{5} structure. They all have the hexagonal symmetry and belong to the space group of P6/mmm. The experimental values of the Curie temperatures (T_{c}) of Nd(Co_{1-x}B_{x})_{5} are used to calculate the effective intersublattice exchange interactions (J_{NdCO}) between Nd and Co sublattices. As the Β content increases, a tendency to decrease in J_{NdCO} and T_{c} is found. This variation is compared with that observed for the Co magnetic moment.
