Abstract: | Raman at 298 and 77 K and infrared spectra of two samples of sodium‐zippeite were studied and interpreted. U? O bond lengths in uranyl were calculated and compared with those inferred from the X‐ray single crystal structure data of a synthetic sodium‐zippeite analogue. Hydrogen‐bonding network in the studied samples is discussed. O? H…O bond lengths were calculated and compared with those predicted from the X‐ray single crystal structure analysis.
