AuDHDH would be gold dideuteride dihydride. Probably not possible as it is because gold doesn’t have a +4 state, but a 1:1 mixture Au(V)DHDHD and AU(III)HDH together could be written informally as AuDHDH.
The main problem with that is that no isotope of hydrogen is electronegative enough put gold into the +5 state.
Yeah, D is used for deuterium.
