摘要: Raman spectrum of the mineral derriksite Cu4UO2(SeO3)2(OH)6⋅H2O was studied and complemented by infrared this mineral. Both spectra were interpreted partly compared with demesmaekerite, marthozite, larisaite, haynesite piretite. Observed bands attributed to (UO2)2+, (SeO3)2−, (OH)− H2O vibrations. The presence symmetrically distinct hydrogen bonded molecule water crystallization hydroxyl ions inferred from in unit cell. Approximate U–O bond lengths uranyl O–H⋯O calculated derriksite.
