The structure of a synthesised compound was confirmed by 1H-NMR and 13C-NMR spectra recorded on the Brucker AC 200F (Germany) apparatus (1H – 200 MHz and 13C – 50 MHz) in deuterated dimethylsulfoxide (d6-DMSO). Chemical shifts are expressed as a δ value (ppm). The multiplicity of resonance peaks is indicated as singlet (s), doublet (d), triplet (t), quartet (q), and multiplet (m). Infrared spectra were recorded on the Perkin-Elmer Spectrum 100 FT-IR spectrometer (PerSeptive Biosystems, Houston, TX, USA) as KBr pellets (4000–450 cm−1). Mass spectra were recorded using a Mariner mass spectrometer (USA). Melting points were determined on the Buchi 535 (GER) melting-point apparatus, and were uncorrected. Elemental analysis of C, H, and N was performed on a Perkin-Elmer 240 analyser (USA), and satisfactory results within ±0.4% of calculated values were obtained.

Complex 1 was synthesized as follows: H2L (212 mg, 0.80 mmol, 2 equiv.) and Co(BF4)2 6 H2O (136 mg, 0.40 mmol, 1 eqequiv.) were dissolved in acetonitrile (10 ml) and NEt3 (0.5 ml) was added. The reaction mixture was stirred at room temperature. Diffusion of diethylether into the acetonitrile solution yielded pink crystals (250 mg, 0.32 mmol, 80%) of the desired complex. Those were also suitable for X-ray analysis. Elem. Anal. Calc. for C28H50CoN6O8S4 0.15 H2O C 42.65; H 6.41; N 10.66% found C 42.66; H 6.75; N 10.63%.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
