Abstract

The structures of [Co2(Eta)3(EtaH)3](ClO 4)3·1/2H2O and [Ni2(Eta)2(EtaH)4](ClO4)2 (where EtaH represents 2-aminoethanol and Eta represents the anion formed by removing the alcohol proton from 2-aminoethanol) have been determined crystallographically, and both structures contain dinuclear cations made up of tris chelates joined face-to-face by oxygen-hydrogen-oxygen bonds. The nickel cations occupy sites of 3 symmetry, the oxygens form an octahedron with hydrogens on four edges, the oxygen-oxygen distances are 2.68 (5) and 2.73 (2) Å, and the octahedral tris chelates have configurations Δλλλ and Λδδδ. The cobalt cations occupy sites of twofold symmetry, the oxygens form a trigonal prism with hydrogens on three edges, the oxygen-oxygen distances are 2.38 (1) and 2.445 (7) Å, and the octahedral tris chelates of one dinuclear unit have the Λδδλ configuration. The compound [Co2(Eta)3(EtaH)3](ClO4) 3·1/2H2O crystallizes in space group P2/c with two formula units in a unit cell of dimensions a = 12.127 (4) Å, b = 8.781 (3) Å, c = 16.524 (6) Å, β = 121.39 (2)°, ρexptl = 1.740 g/cm3, and ρcalcd = 1.745 g/cm3. The structure was solved by Patterson methods, and least-squares refinement converged at final values of R = 0.062 and Rw = 0.076. The compound [Ni2(Eta)2(EtaH)4](ClO4)2 crystallizes in space group Pa3 with four formula units per unit cell with a = 13.85 (1) Å, ρexptl = 1.65 g/cm3, and ρcalcd = 1.67 g/cm3. The structure was solved by Patterson methods, and least-squares refinement converged at final values of R = 0.073 and Rw = 0.052.
