  It seems that so far MP2 method has been implemented for polymers only.
 Check the following paper:
  "Analytical energy gradients in second-order Moller-Plesset perturbation
 theory for extended systems"
  S. Hirata and S. Iwata, J. Chem. Phys. 109, 4147 (1998).
  The paper references most of the people working in this area.
 Specifically, these are
 S. Suhai
 J. Q. Sun and R. J. Bartlett
 S. Hirata and S. Iwata
  Sun and Bartlett did some studies about convergence of the required MO
 integrals:
 Second-order many-body perturbation-theory calculations in extended
 systems.
