N2 -   The two triazido chromium(III) complexes [Cr(tame)(N3)3]×H2O (1) and [Cr(tacn)(N3)3] (2) (tame  = 1,1,1-tris(aminomethyl)ethane and tacn = 1,4,7-triazacyclononane) have been prepared and characterized by single-crystal X-ray crystallography at 122 K. The crystal structure of 1 is monoclinic, space group P21/c, with a = 9.2460(9), b = 11.0500(11), c = 13.1980(9) Å, b = 97.244(7)° with four formula units in the cell. The crystal structure of 2 is triclinic, space group P , with a = 7.698(4), b = 8.5800(6), c = 10.236(3) Å, a = 89.497(15), b = 83.70(2), g = 72.83(2)° with two formula units in the cell. The reactions between NOBF4  and 1 or 2 in acetonitrile give [Cr(tame)(NCCH3)3](BF4)3, and [Cr(tacn)(NCCH3)3](BF4)3, respectively.
