Multi-Dimensional Structures Constructed by the Electrostatic Interaction of Potassium Salts of Cobalt(III) and Manganese(III) Complexes with 1,2-Bis(2-hydroxybenzamido)benzene

Potassium salts of cobalt(III) and manganese(III) complexes, K[CoL(py)₂]·2EtOH·MeOH 1 and K[MnL(py)₂]·py 2, have been prepared, where H₄L= 1,2-bis(hydroxybenzamido)benzene and py = pyridine. 1 crystallizes in the monoclinic space group P2₁/n with the cell dimensions of a= 12.688(3), b= 17.555(4), c= 16.673(3) Å, β = 102.59(2)°, V= 3624(1) ̊³ and Z = 4, in which potassium ion plays a role of connector for two adjacent [CoL(py)₂]^- molecules through K-O interaction (two phenoxo oxygen atoms of a cobalt(III) complex, two oxygen atoms of the solvent molecules, and an amido oxygen of the adjacent unit) to give an extended one-dimensional structure. 2 crystallizes in the orthorhombic space group P2₁2₁2₁ with the cell dimensions of a= 14.358(1), b= 16.457(2), c= 13.703(2) ų, V = 3237.7(5) ų and Z = 4, in which potassium ion plays a role of connector for three adjacent [MnL(py)₂]^- molecules through K-O interaction to give an extended three-dimensional structure.
