%X The crystal structure of the title compound, [Co(C2N2H8)2(C3N2H4)(SO3)] ClO4,2H2O has been determined by X-ray diffraction, using diffractometer data, at 295 K, and refined by full-matrix least squares to a residual of 0.071 for 3425 ?observed? reflections. Crystals are orthorhombic, Pcmn, a 15.822(9), b 11.924(6), c 9.261(2) &#506;, Z 4. The imidazole and sulfite ligands are trans in the cation, which has m symmetry (Co-S 2.223(2); Co-N 2.008(4) &#506;). <Co-N(en)> is 1.964&#506;. The apparent thermal motion of the sulfite about the Co-S axis is very high. The internal internuclear distances are compared to the data reported for series of similar complexes in which trans effects are observed.
