  Structural properties of a finite number ($N = 2 - 20$) of point charges
(classical electrons) confined laterally in a two-dimensional two-minima
potential are calculated as a function of the distance ($d$) between the
minima. The particles are confined by identical parabolic potentials and repel
each other through a Coulomb potential. Both ground state and metastable
electron configurations are discussed. At zero distance previous results of
other calculations and experiments are reproduced. Discontinuous transitions
from one configuration to another as a function of $d$ are observed for $N = 6,
8, 11, 16, 17, 18, 19$.
