Chukanov, S.M. Aksenov, R.K. Rastsvetaeva, K.A. Lysenko, D.I. Belakovskiy, G. Farber, G. Mohn and K.V. Van (2015) Antipinite, KNa3Cu2(C2O4)4, a new mineral species from a guano deposit at Pabellon de Pica, Chile. Mineralogical Magazine, 79(5), 1111–1121. Antipinite (IMA 2014-027), ideally KNa3Cu2(C2O4)4, was discovered in the guano deposit at the lower part of the northern slope of Pabellon de Pica Mountain, Tarapaca Region, Chile. The new mineral honors Mikhail Yuvenal’evich Antipin (1951–2013), a Russian specialist in the crystallography and crystal chemistry of organometallic and coordination compounds. Antipinite occurs in association with halite, salammoniac, chanabayaite, and joanneumite. The host gabbro consists of amphibole, plagioclase, minor clinochlore, and accessory chalcopyrite. Antipinite forms isometric and short prismatic crystals up to 0.1×0.1×0.15 mm, and random aggregates up to 0.6 mm across. The new mineral is blue, translucent, with pale blue streak and a vitreous luster. It is brittle, with a Mohs hardness ~2. The cleavage is medium in three directions, which were not determined. D meas = 2.53(3) and D calc = 2.549 g/cm3. Antipinite does not fluoresce under UV radiation. It is optically biaxial (+), α = 1.432(2), β = 1.530(2), and γ = 1.698(5) (λ = 589 nm); 2 V meas …
