Description	Vajdakite, a new mineral from Jáchymov, NW Bohemia, Czech Republic, forms minute acicular gray-green crystals associated with arsenolite, scorodite, parascorodite, kaňkite, annabergite, köttigite, pyrite, marcasite, nickelskutterudite, and löllingite. Microprobe analysis gave (wt%): As 27.72, Mo 35.39, O 36.66, totaling 99.77. The simplified chemical formula is [(Mo6+O2)2(H2O)2 As3+2O5] . H2O. The mineral is monoclinic, P21/c, a = 7.0515(6), b = 12.0908(9), c = 12.2190(14) Ĺ, b = 101.268(9) °, V = 1021.7(2) Ĺ3, Z = 4, Dmeas = 3.50(2) g/cm3, and Dcalc = 3.509 g/cm3. Optically positive, X \|\| b, Z/c = 12ş, elongation positive, birefrigence is 0.28, 2Vcalc = 35.1ş, a = 1.757(2), b = 1.778(2), g = 2.04(1), pleochroism in X ~ Y light greenish gray, in Z yellowish gray. The crystal structure was solved by direct methods.
