Abstract

Two new three-dimensional zinc phosphates I, [NH(CH2)(2)NH2(CH2)(2)NH3](2+) [Zn-5(PO4)(4)](2-), and II, [CN5H6](+) [Zn-2(PO4)(HPO4)](-), where the structure-directing organic amine acts as a ligand, have been synthesized hydrothermally. Crystal data for I: a = 27.071(2), b = 5.215(1), c = 17.920(1)Angstrom beta = 130.3(1)degrees; U = 1930.9(3) Angstrom(3); space group = Cc (no. 9); Z = 4; M = 811.01; D-calc = 2.789 g cm(-3); MoK alpha and for II: a = 8.089(1), b = 12.771(1), c = 10.067(1)Angstrom beta = 105.3(1)degrees; U = 1000.3(2) Angstrom(3); space group = P2(1)/n (no. 14); Z = 4; M = 409.8; D-clac = 2.713 g cm(-3); MoK alpha. Compound I is novel in the sense that it is dominated by the presence of a large number of three-coordinated oxygen atoms (25%), leading to the formation of infinite Zn-O-Zn chains. Thepresence of a distorted bipyramidal ZnO3N2 unit as well as a 2-membered ring in II is noteworthy. These structures are formed by the networking of ZnO4, ZnO3N, PO4 and ZnO3N2 moieties, leading to the formation of three-dimensional structures possessing channels with I forming a 10-membered one-dimensional channel system and II forming two 8-membered channels.
