%X The complex &#91;Co(en)2(DPPZ)&#93; (ClO4)3 (3) has been synthesized, and the crystal structures of this complex and those of &#91;Co(en)2(bpy)&#93; Br(ClO4)2 (1) and &#91;Co(en)2(phen)&#93; Br3 (2) have been determined. Crystal data for (1): M 614 . 13, monoclinic, space group C2/c (No. 15), a 16 . 7834(16), b 16 . 308(3), c 8 . 3167(15) &#197;, &#946; 104 . 932(11)&#176;, V 2199 . 4(6) &#197;, F(000) 1240, Z 4, Dc 1 . 855 g cm&#8722;3, &#181; 2 . 895 cm&#8722;1 , Mo K&#945; (graphite monochromatized) radiation, &#947; 0 . 71073 &#197;, T 293(1) K. Crystal data for (2): M 599 . 07, triclinic, space group P1 (No. 2), a 7 . 7113(11), b 10 . 633(2), c 12 . 9884(18) &#197;, &#945; 85 . 745(15), b 78 . 258(11), &#947; 74 . 967(16)&#176;, V 1006 . 7(3) &#197;, F(000) 588, Z 2, Dc 1 . 976 g cm&#8722;3, &#181;6 . 819 cm&#8722;1 , MoK&#945; (graphite monochromatized) radiation, &#947; 0 . 71073 &#197;, T 293(1) K. Crystal data for (3): M 773 . 44, monoclinic, space group P 21/c (No. 14), a 20 . 296(2), b 9 . 6197(11), c 15 . 725(2) &#197;, &#946; 92 . 850(10)&#176;, V 3066 . 4(6) &#197;, F(000) 1579, Z 4, Dc 1 . 675 g cm&#8722;3 , &#181; 0 . 898 cm&#8722;1 , MoK&#945;(graphite monochromatized) radiation, &#947; 0 . 71073 &#197;, T 293(1) K. In all three complexes the cobalt is in the usual octahedral environment, with the cations being linked by hydrogen bonds between the amine hydrogens and the anions into extended structures.
