The structural, spectroscopic and magnetic properties of two dimeric complexes, [Cu-2(2-MeSnic)(4)(DMSO)(2)] (I) and [Cu-2(2-MeSnic)(4)(DMF)(2)] (II) (where 2-MeSnic = 2-methylthionicotinate, DMF = dimethylformamide and DMSO = dimethylsulfoxide), are reported. The characterization is based on elemental analysis, infrared, electronic and EPR spectra, and magnetic susceptibility measurements over a temperature range of 1.9 - 300 K. Both complexes adopt dimeric paddle-wheel cage structures as revealed by X-ray structure analysis. The dimeric molecule of I is centrosymmetric and centred at the inversion center of the space group P 2(1)/c (Z = 2), while the structure of II contains a crystallographically independent molecule IIa, and a centrosymmetrical molecule IIb which is centred at the inversion centre of the space group P 2(1)/n (Z = 6).
