Description / Table of Contents:
Überstrukturen von Ti2S3(4 H)Überstrukturen in Bezug auf den Typ Ti2S3(4H) (hexagonale Elementarzelle: a, c) sind röntgenorgraphisch für verschiedene Zusammensetzungen untersucht worden; dadurch wurden die geordneten Verteilungen von Titan-Lücken aufgeklärt. Die Raumgruppe von TiS1,46 (bei 500 oder 700°C geglüht), ist Cc, die Parameter der monoklinen Elementarzelle sind: A = 5,9439(5) Å = √3 a, B = 10,295(1) Å = 3a, C = 22,858(3) Å = 2c und β = 90,0°. Die Raumgruppe von TiS1,51 (bei 500, 700 oder 900°C geglüht) ist auch Cc, die Parameter der rechtwinkligen monoklinen Elementarzelle sind: A = 10,286(1) Å = 3a, B = 5,9383(6) Å = √3 a, C = 34,924(5) Å = 3c und β = 90,0°.
Notes:
Superstructures related to 4H type Ti2S3 (hexagonal unit cell: a, c) are examined by the X-ray diffraction work for several compositions, and the ordered arrangements of titanium vacancies are studied. The space group of TiS1.46 annealed at 500 or 700°C is Cc and the parameters of the monoclinic unit cell are: A = 5.9439(5) Å = √3 a, B = 10.295(1) Å = 3a, C = 22.858(3) Å = 2c and β = 90.0°. The space group of TiS1.51 annealed at 500, 700 or 900°C is also Cc and the parameters of the rectangular monoclinic unit cell are: A = 10.286(1) Å = 3a, B = 5.9383(6) Å = √3 a, C = 34.924(5) Å = 3c and β = 90.0°.
