About trihalides with TiI3 chain structure: Proof of pair forming of cations in β-RuCl3 and RuBr3 by temperature dependent single crystal X-ray analyses

Single-crystal X-ray studies on β-RuCl3 and RuBr 3 at different temperatures verified, that both compounds are dimorphic and show reversible phase transitions at 206 K resp. 384 K. In the HT-forms the Aristo-type of the hexagonal TiI3-structure with space group P63/m c m (Z = 2, β-RuCl3 at 293(2) K: a = 6.121(2) A, c =5.655(2) A, RuBr3 at 423(3) K: 6.5215(12) A, c = 5.8851(13) A) has been found, in the LT-forms the RuBr 3-type structure, an orthorhombic distorted variant with space group Pmmn (Z = 4, β-RuCl3 at 170(3) K: a = 10.576(2) A, b = 5.634(1) A, c = 6.106(1) A, RuBr3 at 293(2) K: a =11.2561(16) A, b = 5.8725(12) A, c = 6.4987(9) A). A hexagonal closest packing of X- anions forms the basis of an arrangement of infinite chains with face-connected [RuX6/2] octahedra. While in the chains of the hexagonal HT-forms the Ru-Ru-distances are identical (d(Ru-Ru) = 2.8275(10) A for β-RuCl3, d(Ru-Ru) = 2.9425(6) A for RuBr 3), in the orthorhombic structures the chains are distorted through pairing of the ruthenium(III) atoms (d(Ru-Ru) = 2.6328(14) A / 3.0010(15) A for β-RuCl3 at 170(3) K, d(Ru-Ru) = 2.765(1) A / 3.108(1) A for RuBr3 at 293(2) K). The hexagonal metric with a/c= √3 holds also for the orthorhombic LT-forms. Large crystals and the final products of the phase transition from HT- to LT-forms are pseudomerohedral twins of three twin domains with nearly equal amounts complicating proof and analysis of the LT-forms.
