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

摘要

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 H_4L = 1,2-bis(hydroxybenzamido)benzene and py = pyridine. 1 crystallizes in the monoclinic space group P2_1 with the cell dimensions of a = 12.688(3), b = 17.555(4), c = 16.673(3) A, β = 102.59(2)°, V = 3624(1) A~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 P2_12_12_1 with the cell dimensions of a = 14.358(1), b = 16.457(2), c = 13.703(2) A, V = 3237.7(5) A~3, 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.
