The nonlocalized clustering approach is generalized to Be isotopes with isospin dependent spin–orbit potential. A new form of the Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function is introduced to provide a correct description for the 
-binding neutron in 
Be. Systematic calculations for Be isotopes are performed and results fit well with experimental values. The low energy spectrum of Be is also obtained, especially the correct spin-parity 
is reproduced for the intruder ground state. The exotic neutron halo structure of Be is studied by calculations of root-mean-square radii and density distribution. The spectroscopic factor is also calculated and discussed for the 
ground state of 
Be.
