A new, unusual Fe-free and As⁵⁺-enriched variety of chladniite, a rare phosphate of the fillowite group was found in exhalations of the active Arsenatnaya fumarole, Tolbachik volcano, Kamchatka, Russia. It belongs to the high-temperature (500–750°С) paragenesis with calciojohillerite, fluorapatite, metathénardite, diopside, enstatite, forsterite and hematite. This genetic type is novel for fillowite-group minerals. The crystal structure of Tolbachik chladniite is solved, R1 = 4.32%. It is trigonal, R–3, a = 14.9831(2), c = 42.8050(7) Å, V = 8322.1(3) Å³. The structural formula is: ^M13(Na_{0.56\(\square \)0.44})\(_{2}^{{M21}}\)(Na_0.81Ca_0.19)\(_{2}^{{M31}}\) (Na_{0.97\(\square \)0.03})\(_{6}^{{M12}}\)(Ca_0.64Na_0.36)\(_{6}^{{M1}}\)Mn^M2(Mg_0.54Ca_0.46)^M3–9Mg\(_{{30}}^{{M10}}\)(Mg_0.94Ca_0.06)\(_{6}^{{M11}}\)Mg₆(P_33.53As_2.47)O₁₄₄ (Z = 3). The crystal chemical features of chladniite and their correlation with mode of occurrence are discussed for all chladniite findings known in meteorites and terrestrial objects of different genetic types.
