An ab initio study of the molecular geometry and stability of Y(H 2 O) 3+ n( n = 1–10) clusters at the restricted Hartree–Fock (RHF) and second‐order Møller–Plesset (MP2) levels is reported. The results obtained indicate that in aqueous solutions, the Y 3+ ion is primarily 8‐coordinate. The most popular DFT functionals were tested to calculate the dimensions of the Y(H 2 O) 3+ 8aqua ion. It was found that SVWN5, SPL, BHandH, B3P86, and PBE1PBE functionals give the closest results to the experimental YO distance. © 2006 Wiley Periodicals, Inc. Int J Quantum Chem, 2006
