Synthesis and Characterization of Neutral, Four-Coordinate, Tetrahedral Kanganese(II) Complexes Involving Coordinated Chloro and Thiocyanato Groups in the Solid State

Abstract

Preparations of Mn(2,6-dimethylpyridine-N-oxide)₂Cl₂ and Mn(pyrazine)₂(NCS)₂ have been described. Based on room temperature magnetic moment values, electronic spectral, ligand field parameters and infrared spectral features down to 200 cm⁻¹ the complexes isolated are considered as neutral species of four-coordinated, high spin, monomeric, tetrahedral environments around manganese(II) invovling coordinated chloro and thiocyanato groups in the solid state.
