| Species: | Zinconigerite-6N6S |
| Formula: | Zn3Sn2Al16O30(OH)2 |
| Comments: | First described by Burke et al (1977) as Fe-rich nigerite. At the time of their study the polysome was not known. Using the reported XRD data Armbruster (2002) argumented and showed that the material according to new nomenclature can be named zinconigerite-6N6S. |
