A new synthesis route to the ${\pi }$-d ferrimagnet TTF[ Cr(NCS) 4(1,10 '-phenanthroline)] is described along with recent magnetic investigations. In particular the variable frequency AC magnetisation of the protonated and fully deuterated samples indicate no frequency dependence and a T $_{\rm c}$ of 8.7 K. Single crystal heat capacity and muon spin relaxation experiments show a second magnetic transition at 2.4 K. Key words. Charge-transfer salts, conductivity, ferrimagnetism.
