Abstract
Single crystals of Zn4FeII5(PO4)6.4H2O were grown by hydrothermal treatment of phosphophyllite (Zn2Fe(PO4)2.4H2O) in H2O at 180-degrees-C. The crystal structure (tricl., P1BAR; a = 651.6(4) pm, b = 902.7(4) pm, c = 995.4(4) pm, a = 69.01(5)-degrees, beta = 78.19(5)-degrees, gamma = 75.33(5)-degrees; Z = 1) can be derived from the Zn2(Zn1-xFex)FeIII(PO4)3.2H2O structure by reduction of Fe(III) to Fe(II) and by filling a ,,structure hole'' with an additional Fe(II).
