N2  - The crystal structure of the title compound, [Co((C5H4N)3N)2] (ClO4)2, has been determined by single-crystal X-ray diffraction at 295(1) K, i.e. in its pseudo-'high-spin' form, and refined by least squares to a residual of 0.061 for 4639 'observed' reflections. Crystals are monoclinic, P21/a, a 12.811(7), b 17.644(7), c 8.375(4) &#506;, &#946; 120.15(3)&#176;, Z 2. Whereas in the iron(II) ('low-spin') analogue, the metal atom coordination geometry deviates only trivially from octahedral (<Fe-N> 1.982 &#506;, <N-Fe-N> within the one ligand 88.1&#176;), in the present compound Co-N ranges from 2.100(2) to 2.152(2) &#506; and the intraligand N-Co-N angles range from 84.86(7) to 86.09(8)&#176;.
