Bm11 chord

The B minor eleventh chord (abbreviated Bm11 chord) is a six-note chord consisting of the notes B, D, F♯, A, C♯, and E. The chord is formed by adding an eleventh to the B minor ninth chord.

In practice, the fifth (F♯) is often omitted from the Bm11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
