N2  - The crystal structure of the title compound, [Co(C9H13N5)2] I2,H2O, has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.058 for 3255 'observed' reflections. Crystals are triclinic, P&#299;, a 14.934(5), b 11.315(4), c 8.090(3)&#506;, &#945; 85.19(3), &#946; 87.76(3), &#947; 74.10(3)&#176;, Z 2. The distances from the cobalt to the central trimethine nitrogen atoms are 1.893(8) and 1.903(8)&#506; consistent with the almost low-spin behaviour of the complex; the distal Co-N distances range between 2.045(8) and 2.140(8)&#506;. One of the iodide anions appears to be disordered over two sites populated in the ratio 0.86:0.14; occupancy of the second site together with the magnetic moment of 2.1 BM may indicate a small proportion of the high-spin isomer.
