    Description / Table of Contents: Summary The crystal structure of the new mineral warikahnite, Zn3[(H2O)2|(AsO4)2], was determined from diffractometer data and refined toR=0,038 for 3428 observed independent reflections. Warikahnit is triclinic, $$P\bar 1$$ , witha=6.710(1),b=8.989(2),c=14.533(2) Å, α=105.59(1), β=93.44(1), γ=108.68(1)°,Z=4. The crystal structure of warikahnite contains 6 different coordination polyhedra of zinc with the coordination numbers 6,5 and 4 and with 5 different combinations of ligand. The hydrogen bonds are discussed on the basis of charge balance and IR spectra.
