摘要
Employing 1-(2-Aminoethyl) piperazine as a template, a new organically templated layered zinc phosphate-phosphite (C6H17N3)[Zn-4(PO4)(2)(HPO3)(2)] has been prepared hydrothermally. Single-crystal X-ray diffraction analysis shows that it crystallizes in the monoclinic space group Cc with a = 5.3272(11) Angstrom, b = 17.146(3) Angstrom, c = 22.071(4) Angstrom, beta = 94.58(3)degrees, V = 2009.5(7) Angstrom(3), Z = 4, R-1 = 0.0201 (I > 2sigma(I)) and wR(2) = 0.0812 (all data). The inorganic network is based on strictly alternating ZnO4 tetrahedral units and P-centered units including PO4 tetrahedra and HPO3 pseudo-pyramids forming a double layered structure that contains columns of double six-membered rings. The diprotonated 1-(2-Aminoethyl) piperazine molecules reside in the interlayer region and interact with the inorganic network through H-bonds. (C) 2004 Elsevier Inc. All rights reserved.
