...Emil Makovicky Abstract Crystal structures of the three polymorphs of Cu 5 (PO 4 ) 2 (OH) 4 , namely pseudomalachite, ludjibaite, and reichenbachite, can be described as being composed of rods perpendicular to their crystal-chemical layering. Two different sorts of rods can be defined. Type 1 rods...

... 01 2002 © 2003 American Mineralogist 2003 Several dark green copper phosphate minerals are known to exist, including pseudomalachite [Cu 5 (PO 4 ) 2 (OH) 4 ], ( Anthony et al. 2000 ) and its polymorphs reichenbachite and ludjibaite ( Braithwaite and Ryback 1994 ; Hyrsl 1991 ; Lhoest...

... ) 2 (OH) 4 , although once you find pseudomalachite, ludjibaite or reichenbachite, the other two are listed as the polymorphs. For this reviewer organization by a chemical classification would be preferable. One great advantage this work has over other standard mineralogical works currently in print...

... was then cooled to room temperature, and the crystals were washed several times with deionized water. Other attempts (with variations of the molarity of Cu and PO 4 and amount of NH 4 OH) yielded mixtures of libethenite, ludjibaite, and clinoatacamite. Fig. 1.
