The STO-nG basis sets were first published by Hehre, Stewart, and Pople in 1969:

Variational (Rayleigh-Ritz) method and multielectron wavefunction
One Electron
Starting with your trial wavefunction:
$$
\Phi = \sum^k_{i=1} c_i \chi_i,
$$
you seem to be thinking about one-electron orbitals $\chi_i(r)$ which will add up to a one-electron molecular ...
