Abstract: 

The compounds Ln3TiO4Cl5 have been prepared by reaction of LnCl3/LnOCl/TiO2 (1:2:1) (Ln = La-Nd) in evacuated silica ampolues. Single crystals of La3TiO4Cl5 were obtained by chemical transport reaction (T2 --> T1; T2 = 1050-degrees-C, T1 = 950-degrees-C) using chlorine (p(Cl2; 298 K) = 1 atm) and sulfur as transport agents with La2TiO5 as starting material.

La3TiO4Cl5 crystallizes in the orthorhombic space group Pnma (No. 62) with cell-dimensions a = 16.760(2) angstrom, b = 4.0991(6) angstrom, c = 14.634(2) angstrom, Z = 4. The structure was refined to give R = 4.76%, R(w) = 2.47%. Main building units are TiO5 trigonal bipyramides and threefold capped trigonal prisms around La. The relationship to La2TaO4Cl3 will be discussed.
