Using metallic Ti powder as raw materials and 1,2-diaminocyclohexane (DACH) as the trial template, two novel reduced titanophosphate open-structures were hydrothermally isolated by varying the $H_3PO_4/H_2O$ ratio to adjust the pH value. TiPO-1 crystallizes in orthorhombic Pbca space group with cell parameters a = 21.956(3) $AA$, b = 8.6268(11) $AA$, c = 7.2883(9) $AA$, V = 1380.5(3) $AA^3$, Z = 4. TiPO-2 crystallizes in triclinic space group P$ar{1}$ with parameters a = 5.1620(10) $AA$, b = 8.815(2) $AA$, c = 10.655(3) $AA$, $alpha$ = $99.45^{circ}$, $eta$ = $102.94^{circ}$, $gamma$ = $91.06^{circ}$, V = 465.34 $AA^3$. TiPO-1 is constructed by infinite -Ti-O-Ti-O- linkage that is capped by $PO_4$ groups to form a chain structure with protonated DACH molecules occupying the interchain spaces. TiPO-2 represents a rare 3-D reduced titanophosphate with 12-MR channels. The structure of TiPO-2 is a neutral framework with water molecules located in the channels.
