Abstract: The organically templated titanium phosphate [Ti3P6O27 H5] · [C2H9N2]5·2 [H3O] has been synthesized by solvothermal method and its structure was determined by single crystal Xray diffraction. The crystal crystallizes in a orthorhombic system of the enantiomorphic space group P212121 , with a = 1.0180(6) nm , b =1.5899(9) nm, c =2.3227(12) nm, V =3.7594(4) nm3, Z =4, Dc= 1.96 g/cm3 , F (000)= 2296 , R =0.0486, ωR2=0.1257. The title compound contains chiral spirals formed from macroanionic chains of titanium oxygen octahedra bonded together by phosphate tetrahedral. These spirals are interconnected through hydrogen bonding in a manner to form unusual tunnels along the [001] direction in which H2N(CH2)2NH3+ cations are included. Second harmonics are generated in powdered sample.

Key words: Template synthesis, Solvothermal method, 1D Chiral chain, Titanium phosphate
