The title compound (C6N3H18)2Ti4O4(C2O4)74H2O 1 (C13H22N3O18Ti2, Mr = 604.14) was synthesized by the reaction of Ti(SO4)2, H2C2O42H2O and N-(2-ammonioethyl)- piperazinium (AEPP) in aqueous solution. The single-crystal X-ray analysis has revealed that 1 crystallizes in the triclinic system, space group Pi with a = 9.1437(6), b = 11.4991(10), c = 11.6975(8) ? a = 96.2915(18), ?= 107.998(3), ? = 104.276(4), V = 1110.35(14) ?, Z = 2, Dc = 1.807 g/cm3, F(000) = 618, ?= 0.815 mm-1, the final R = 0.0463 and wR = 0.1264 for 3718 observed reflections with I > 2s(I). X-ray crystal-structure analysis suggests that compound 1 consists of [Ti4O4(C2O4)7]6- anion and two protonated N-(2-ammonioethyl)piperazinium cations. The anions are linked into an infinite chain through Ti4O4(C2O4)8 by sharing the oxalates as bridging ligands.
