Coordination Compounds of 2-Hydroxy-4,6-diphenyl-thiobenzophenone. Chelate Complexes of Cobalt and Nickel, X-ray Structure of the Nickel Compound2-Hydroxy-4,6-diphenyl-thiobenzophenone (HL) reacts under deprotonation with metal salts to chelate complexes. The reactions with nickel acetate or cobalt acetate yield neutral complexes of the composition NiL2 and CoL3, respectively. The nickel compound crystallizes monoclinic in the space group P21/c (No. 14), a = 17.55(6), b = 26.69(4), c = 8.49(9) Å, β = 102.7(2)°, Z = 4. The nickel atom has a distorted squareplanar coordination sphere. The ligands are cis coordinated.
Notes:
2-Hydroxy-4,6-diphenyl-thiobenzophenon (HL) reagiert unter Deprotonierung mit Metallsalzen zu Chelatkomplexen. Die Umsetzung mit Ni— bzw. Co-Acetat führt zu neutralen Komplexen der Zusammensetzung NiL2 bzw. CoL3. NiL2 kristallisiert monoklin in der Raumgruppe P21/c (Nr. 14); a = 17,55(6); b = 26,69(4); c = 8,49(9) Å; β = 102,7(2)°; Z = 4. Das Nickelatom befindet sich in einer verzerrt quadratisch-planaren Koordinationssphäre. Die Liganden nehmen die cis-Konfiguration ein.
