The electric quadrupole moment for the 5d {sup 2}D{sub 3/2} state of {sup 171}Yb{sup +}, has been calculated using the relativistic coupled-cluster method. Earlier a similar calculation was performed for the 4d {sup 2}D{sub 5/2} state of {sup 88}Sr{sup +} which is the most accurate determination to date [Sur et al., Phys. Rev. Lett. 96, 193001 (2006)]. The present calculation of the electric quadrupole moment of {sup 171}Yb{sup +} yielded a value 2.157ea{sub 0}{sup 2} where the experimental value is 2.08(11)ea{sub 0}{sup 2}; a{sub 0} is the Bohr radius and e the elementary charge. We discuss in this paper our results for {sup 171}Yb{sup +} in detail and highlight the dominant correlation effects present. We have presented the effect of inner core excitations and their contribution to the electric quadrupole moment, which is a property sensitive to regions away from the nucleus.
