Structure and magnetism of Sr3Co2O4Cl2--an electronically driven lattice distortion in an oxychloride containing square planar Co(II) centers.

Topochemical reduction of Sr(3)Co(2)O(5)Cl(2) with NaH at 200 °C yields Sr(3)Co(2)O(4)Cl(2), a phase consisting of infinite double sheets of corner-linked Co(II)O(4) square planes stacked with SrCl rocksalt layers. At 298 K, the structure of Sr(3)Co(2)O(4)Cl(2) is described in the tetragonal space g...
