Cobalt(II) perchlorate

Cobalt(II) perchlorate is an inorganic chemical compound with the formula Co(ClO4)2·nH2O (n = 0,6).

The pink anhydrous and red hexahydrate forms are both hygroscopic solids.

Instead, anhydrous cobalt(II) perchlorate is produced from the reaction of dichlorine hexoxide and cobalt(II) chloride, followed by heating in a vacuum at 75 °C.

[1][2] The anhydrous form consists of octahedral Co(ClO4)6 centers, with tridentate perchlorate ligands.

The hexahydrate undergoes phase transitions at low temperatures.
