A zinc phosphate,[NH<SUB>3</SUB>(CH<SUB>2</SUB>)<SUB>3</SUB>NH<SUB>3</SUB>] [Zn<SUB>4</SUB>(PO<SUB>4</SUB>)<SUB>2</SUB>(HPO<SUB>4</SUB>)<SUB>2</SUB>], possessing alternate inorganic and organic layers

A new zinc phosphate of the formula, [NH3(CH2)3NH3][Zn4(PO4 )2(HPO4)2], has been synthesized hydrothermally starting from a zinc amine complex. It crystallizes in the monoclinic space group C2/c; a=17.279(1), b=5.193(1), c=20.115(1) &#197;, &#946;=92.6(1)&#176;; V=1803.1(2) &#197;3; Z=4; Dcalc=2.05 g cm-3; &#956; (MoK&#945;)=5.62 mm-1. The final R, and wR2=0.037, 0.093 obtained for 136 observed data [I&gt;2&#963;(I)]. The structure consists of macroanionic sheets of interconnected ZnO4 and PO4 tetrahedra in the ab plane. The sheets are held together by hydrogen bond interactions with the organic structure-directing amine, forming alternate inorganic-organic layers in this material. Hydrogen bond interactions between the inorganic layers, via the terminal -OH group, leads to the formation of pseudo one-dimensional channels
