Abstract
The cis isomer of the title compound, [Cr(NCS)(2)(C10H24N4)](ClO4), is a racemate of the Bosnich type V structure; the trans complex is a me so substance with a Bosnich type III stereochemistry. There is no appr eciable change in the structures of the title compound on cooling, eve n though there are marked color changes. The Cr-N bond lengths are all in the range 1.983 (2)-1.998 (4) Angstrom for the bonds to the isothi ocyanate groups and in the range 2.046 (2)-2.088 (3) Angstrom for the bonds to cyclam N atoms.
