“…The synthesis of the molecular precursor [Mo(S 2 CNEt 2 ) 4 ] (MoL 4 ) followed the method of Decoster et al whereby 3.0 g of molybdenum hexacarbonyl was heated in 100 mL of acetone in the presence of 6.8 g of tetraethylthiuram disulfide and held under reflux for 2 h. The resulting mixture was allowed to cool slowly, and the dark-purple microcrystalline powder formed was isolated by suction filtration and washed with pentane (5.6 g, 71%). Anal.…”

“…Recent susceptibility measurement using a SQUID magnetometer indicate a possible structural phase transition in 2b near 250 K. , From the structural analysis we believe the stacking of TCNQ dimers modifies from slipped to eclipsed state. We then decided to perform optical measurements at low temperature to gain further information on these structural modifications.…”

“…These experiments realized in a liquid−crystalline phase are in agreement with the results obtained from solutions and with those on the isolated monomeric state solid [ ](TCNQ) which crystallizes in two different structural forms, the first one with isolated TCNQ monomers, and the second one with isolated TCNQ dimers. X-ray structural data, magnetic measurements and optical spectra are thus strongly in favor of monomeric isolated species of TCNQ •- in the complex 2a . Our results are presented in Table and compared to the literature. 3 Optical spectrum of complex 2a ( T = 293 K).…”

“…The synthesis of molecular precursors CrL 3 and MoL 4 was carried out according to Scheme 1. CrL 3 was produced by simple direct reaction of the ligand and chromium(III) chloride, whereas MoL 4 was produced by oxidative addition of tetraethyl dithiuram to molybdenum(0) hexacarbonyl according to the method of Decoster et al 35 The yield of the former reaction was markedly low due to the difficulty in preparing (N,N-dithiocarbamato)chromium(III) complexes. 39 Elemental analysis, infrared spectroscopy, and mass spectrometry confirmed the purity of the complexes.…”
