✦ Synopsis
Thhe restricted CNDOl.5 LHP method hss bern employed TO calculate the pymzil~*z-lithium systcm_The ch~ge transfer from lithium to pyrazinc is interpreted. It is shown that Li+ lias in the plant: of the pyrazine ring in the direction of the nitrogen lone-pair electrons. The stabilization of this ion pair is stroqly supported by solwtion energy.
