Struktur dan sifat
Asam metanaseleninat telah dikarakterisasi melalui kristalografi sinar-X.[4] Konfigurasi atom selenium berbentuk piramida, dengan Se-C = 1,925(8) Å, Se-O = 1,672(7) Å, Se-OH = 1,756(7) Å, sudut OSeO = 103,0(3)°, sudut HO-Se-C = 93,5(3)°, dan sudut OSeC = 101,4(3)°. Strukturnya isomorf dengan asam metanasulfinat.[5]
Asam benzenaseleninat (C6H5−Se(=O)−OH) sebelumnya telah dikarakterisasi melalui metode sinar-X[6] dan resolusi optiknya telah dilaporkan.[7]
