摘要：

The title compound, Zn-6(PO4)(4)(HPO4)(H2O)(H3NCH2CH2NH3), was synthesized at room temperature under acidic conditions. Large crystals for structure determination were grown hydrothermally at 170 degrees C. The compound crystallizes in the monoclinic space group C2/c (no. 15) with a = 19,129(6), b = 5.0304(7), c = 21,148(6) Angstrom, and beta = 103.27(1)degrees. The structure is an open framework of PO4 and ZnO4 tetrahedra with two types of one-dimensional channels along b (the larger are occupied by the ethylenediamine dication whereas the smaller contain water and hydroxyl groups), There is extensive Zn-O-Zn bonding in the structure in the form of dimers and infinite chains of corner-sharing ZnO4 tetrahedra. The compound can be fully dehydrated at 380 degrees C and is stable up to 450 degrees C.
