Abstract

The title compound, [Co(C₁₈H₃₇N₂)₂(NCS)₄], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabi-cyclo-[2.2.2]octane (DABCO⁺) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octa-hedral coordination environment of the Co^II ion is completed through four N atoms of iso-thio-cyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C-H⋯N and C-H⋯S between the filamentous mol-ecules lead to the formation of layers parallel to (001).

Keywords: DABCO; Isothiocyanate; cobalt(II) complex; crystal structure.
