The chord chart below lists the common traid and four note extended chords belonging to the key of C harmonic minor. Roman numerals indicate each chords position relative to the scale.
The triad and extended (four voice) chord sequence derived from the harmonic minor scale are as follows
Chord progressions using the harmonic minor scale will often be mixed with chords taken from the other minor scales. It's common therefore to see something like i - iv - V7 progressions where the V7 is taken from the harmonic minor while the rest of the chords are taken from the natural minor.
This is explained in more detail in the chord theory pages
