Structure Determination Of Ba8Corh6O21, A New Member Of The 2h-Perovskite Related Oxides, Hans Conrad Zur Loye, M. D. Smith, K. E. Stitzer, A. El Abed, J. Darriet
Structure Determination Of Ba8Corh6O21, A New Member Of The 2h-Perovskite Related Oxides, Hans Conrad Zur Loye, M. D. Smith, K. E. Stitzer, A. El Abed, J. Darriet
Hans Conrad zur Loye
Single crystals of Ba8CoRh6O21 were grown out of a potassium carbonate flux. The structure was solved by a general method using the superspace group approach. The superspace group employed was R3m(00γ)0s with a = 10.0431(1) Å, c1 = 2.5946(1) Å and c2 = 4.5405(1) Å, V = 226.60(1) Å3. Ba8CoRh6O21 represents the first example of an m = 5, n = 3 member of the A3n+3mA'nB3m+nO9m+6n family of 2H hexagonal perovskite related oxides and contains chains consisting of six …
Growth Of Sr6Rh5O15 Single Crystals From High Temperature Solutions: 1. Structure Determination Using The Traditional 3d And The 4d Superspace Group Methods. 2. Magnetic Measurements On Oriented Single Crystals, Katherine Stitzer, Ahmed Abed, Jacques Darriet, Hans Conrad Zur Loye
Growth Of Sr6Rh5O15 Single Crystals From High Temperature Solutions: 1. Structure Determination Using The Traditional 3d And The 4d Superspace Group Methods. 2. Magnetic Measurements On Oriented Single Crystals, Katherine Stitzer, Ahmed Abed, Jacques Darriet, Hans Conrad Zur Loye
Hans Conrad zur Loye
Single crystals of Sr6Rh5O15 were grown from a molten potassium carbonate flux. The structure was solved by both the traditional 3-D crystallographic approach and the 4-D superspace group approach using JANA2000. Both methods produced an equivalent structure determination, thereby confirming the 4-D superspace group approach as an effective structure solution method for 3-D commensurate composite structures. Sr6Rh5O15 corresponds to the n = 1, m = 1 member of the A3n+3mA‘nB3m+nO9m+6n family of 2H hexagonal …
