Single crystals of Sr6Rh5O15 were grown from a molten potassium carbonate f
lux. 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
= I member of the A(3n+3m)A ' nB3m+nO9m+6n family of 2H hexagonal perovskit
e-related oxides. This compound is characterized by pseudo-one-dimensional
polyhedral chains of four face-sharing RhO6 octahedra followed by one RhO6
trigonal prism. These chains in turn are separated by [Sr](infinity) chains
. Magnetic measurements were carried out on oriented single crystals, and a
very large magnetic anisotropy in the magnetic susceptibility was observed
