【Abstract】 The organically templated titanium phosphate [Ti 3P 6O 27 H 5] · [C 2H 9N 2] 5·2 [H 3O] has been synthesized by solvothermal method and its structure was determined by single crystal X ray diffraction. The crystal crystallizes in a orthorhombic system of the enantiomorphic space group P 2 12 12 1 , with a = 1.018 0(6) nm , b =1.589 9(9) nm, c =2.322 7(12) nm, V =3.759 4(4) nm 3, Z =4, D c= 1.96 g/cm 3 , F (000)= 2 296 , R =0.048 6, ωR 2=0.125 7. 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 H 2N(CH 2) 2NH 3 + cations are included. Second harmonics are generated in powdered sample. [WT5HZ]更多还原
