We thank the Mineralogical Museum of the University of Rome (M.M.U.R.), for having supplied the samples and P. Maistrelli for a copy of the MACDUST software package. The microprobe analyses were made at the Centro di Studio per il Quaternario el'Evoluzione Ambientale del C.N.R. (Roma) under the supervision of Marcello Serracino. The powder XRD data were obtained at Arizona State University, Department of Chemistry on equipment purchased under NSF Grant DMR-8406823. SAED patterns were recorded at the Arizona State University Center for High-resolution Electron Microscopy, which is supported by NSF Grant DMR-9115680 and by ASU. Financial support was partly from the NSF Grant EAR9219376 (to PRB) and M.U.R.S.T. 40%: "Mineralogia regionale, specie mineralogiche."

N2 - Improved powder X-ray diffraction (XRD) data for liottite and sacrofanite, two members of the cancrinite group of minerals, were obtained using a rotating anode diffractometer. The cell parameters of liottite are a = 12.8575(3), c=16.0905(6) A, and the space group is P6m2; the strongest reflections are at 4.834(38), 3.783(12), 3.714(100), 3.312(91), 2.784(13), 2.682(26), 2.470(17), and 2.143(27) A. The cell parameters of sacrofanite are a = 12.8945(4) and c =74.2128(37) A, and the possible space groups are P63/mmc, P63rac, and P62c; the strongest reflections are at 11.18(23), 3.757(25), 3.723(100), 3.488(27), 3.302(62), 2.651(31), 2.645(30), and 2.149(18) A. The new data include an increased number of indexed peaks and empirical formulae that differ from the reference data (PDF 29–1187 and PDF 35–653, respectively).
