The part you circled in red isn't really the chord. It's a non-chord tone device called a suspension.
The twotwo chords involved at that momentsmoment are E
diminished seven (circled in green) and F
minor (circled in blue.)
Notice how those two chords overlap in time. When the bass goes from E
to F
the top voices don't change and hold the tones of the E
diminished seven chord. Those top voices are suspended for a moment when the bass moves. When those top voices move down to the tones of the F
minor chord is called the resolution.
In written harmony analysis, the bass is usually the point where a chord is identified and then non-chord tone symbols can be added on other voices. So you could put some F
minor chord symbol under the F
at the beginning of the bar, but on top of the treble voices you could add a mark "sus" to indicate there is a suspension.
