    Description / Table of Contents: Synthesis and Structure of Cobalt(III) Complexes of 14-Membered cis- and trans-N2S2 Dibenzo Macrocycles with two Pendant Acetato GroupsThe isomeric fourteen membered macrocyclic ligands 6,7,9,15,16,18-hexahydrodibenzo[f,m][1,8]dithia[4,11]diazacyclotetradecine-8,17-diacetic acid-0.5-hydrate (H2L3), C22H26N2O4S2 · 0.5 H2O and 6,7,13,15,16,18-hexahydrodibenzo-[e,m][1,4]dithia[8,11]diazacyclotetradecine-14,17-diacetic acid-1.5-hydrate (H2L6), C22H26N2O4S2 · 1.5 H2O with cis- and trans-N2S2 donorsets and two pendant acetato groups form the stable complexes [Co(L3)]ClO4 · 2 H2O (1) and [Co(L6)]ClO4 · H2O (2). Co(III) is octahedrally coordinated herein to all six donor centers of the respective ligand. The macrocyclic rings are folded. The metal ions are located outside the macrocyclic cavity. The mean Co—N, Co—O and Co—S distances are 196, 190 and 224 pm, respectively.Crystal data: 1, monoclinic, space group C2/c, a = 3 797.7(9), b = 763.8(3), c = 2 207.0(7) pm, β = 123.17(2), Z = 8, 3 445 reflections, R(Rw) = 0.072(0.070); 2, monoclinic, space group C2/c, a = 3 197.1(6), b = 880.4(2), c = 1 890.6(4) pm, β = 112,19(3)°, Z = 8, 4 415 reflections, R(Rw) = 0.062(0.064).
    Notes: Die beiden isomeren Liganden 6,7,9,15,16,18-Hexahydrodibenzo[f,m][1,8]dithia[4,11]diazacyclotetradecin-8,17-diessigsäure-0,5-hydrat (H2L3), C22H26N2O4S2 · 0,5 H2O bzw. 6,7,13,15,16,18-Hexahydrodibenzo[e,m][1,4]dithia-[8,11]diazacyclotetradecin-14,17-diessigsäure-1,5-hydrat (H2L6), C22H26N2O4S2 · 1,5 H2O mit cis- bzw. trans-N2S2-Donorzentren im vierzehngliedrigen makrocyclischen Ring und zwei Acetat-Seitenketten bilden die stabilen Komplexe [Co(L3)]ClO4 · 2H2O (1) und [Co(L6)]ClO4 · H2O (2). CoIII ist jeweils von allen 6 Donorzentren der Liganden oktaedrisch umgeben. Die Liganden sind gefaltet. Die Metallatome liegen außerhalb der makrocyclischen Kavität.Kristalldaten: 1, monoklin, Raumgruppe C2/c, a = 3 797,7(9), b = 763,8(3), c = 2 207,0(7) pm, β = 123,17(2)°, Z = 8, 3 445 Reflexe, R(Rw) = 0,072(0,070); 2, monoklin, Raumgruppe C2/c, a = 3 197,1(6), b = 880,4(2), c = 1 890,6(4) pm, β = 112,19(3)°, Z = 8, 4415 Reflexe, R(Rw) = 0,062(0,064).
