Synthesis and structure of a new open-framework zinc phosphate : [Zn-3(PO4)(2)(HPO4)(0.5)](-)0.5[(NH3(CH2)(2)(NH3)]2+H2O
A new open-framework zinc phosphate, [Zn-3(PO4)(2)(HPO4)(0.5)] (-)[0.5(NH3 (CH2)(2)(NH3)]2+H2O, having Zn-O-Zn linkages was synthesized by hydrothermal technique. The structure consists of a network of ZnO4 and PO4 tetrahedra in which the vertices are shared. Water molecules are present in a 6-membered channel and the protonated ethylenediamine molecule is in the middle of a 8-membered channel, creating alternating hydrophobic and hydrophilic channels.
