(±)Rh(en) 3 (SCN) 3 and (+)Rh(en) 3 (SCN) 3 , Rh(C 2 H 8 N 2 ) 3 .(SCN) 3 , C 6 H 24 N 6 Rh.C 3 N 3 S 3 , crystallize in orthorhombic cells. The lattice constants are respectively a = 14.652 (5), b = 14.268 (6), c = 17.480 (6) Å and a = 14.711 (4), b = 13.481 (3), c = 9.166 (2) Å. They are isomorphic with their homologues (±)Co(en) 3 (SCN) 3 and (−)Cr(en) 3 (SCN) 3 . The active racemate [(+)Rh(en) 3 (+)Cr(en) 3 ](SCN) 6 is isomorphic with the monoclinic form of [(+)Co(en) 3 (−)Cr(en) 3 ](SCN) 6 . Its lattice constants are a = 15.707 (5), b = 17.739 (4), c = 9.426 (3) Å and γ = 131.04 (2)°.
