Abstract

The complex [Co(en)2(DPPz)] (ClO4)3 (3) has been synthesized, and the crystal structures of this complex and those of [Co(en)2(bpy)] Br(ClO4)2 (1) and [Co(en)2(phen)] 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) Å, β 104.932(11)°, V 2199.4(6) Å, F(000) 1240, Z 4, Dc 1.855 g cm-3, μ 2.895 cm-1, Mo Kᾱ (graphite monochromatized) radiation, λ 0.71073 Å, T 293(1) K. Crystal data for (2): M 599.07, triclinic, space group P1̄ (No. 2), a 7.7113(11), b 10.633(2), c 12.9884(18) Å, α 85.745(15), b 78.258(11), ̀ 74.967(16)°, V 1006.7(3) Å, F(000) 588, Z 2, Dc 1.976 g cm-3, μ 6.819 cm-1, Mo Kᾱ (graphite monochromatized) radiation, λ 0.71073 Å, T 293(1) K. Crystal data for (3): M 773.44, monoclinic, space group P21/c (No. 14), a 20.296(2), b 9.6197(11), c 15.725(2) Å, β 92.850(10)°, V 3066.4(6) Å, F(000) 1579, Z 4, Dc 1.675 g cm-3, μ 0.898 cm-1, Mo Kᾱ (graphite monochromatized) radiation, λ 0.71073 Å, 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.
