Reactions with the technetium and rhenium carbonyl complexes (NEt4)2[MX3(CO)3]. Synthesis and structure of [Tc(CN-But)3(CO)3](NO3) and (NEt4)[Tc2(μ-SCH2CH2OH)3(CO)6]

Tetra-μ3-hydroxido-tetrakis[tricarbonylrhenium(I)] pyridine tetrasolvate

“…[NEt 4 ] 2 [Re(CO) 3 Br 3 ] (75 mg, 0.097 mmol), as prepared by Alberto et al (1996), was dissolved in 20 ml of pyridine. The mixture was stirred at room temperature for 3 h and left to stand.…”

Crystal structure of fac-hexacarbonylbisμ2-(3-carboxy-3′-carboxylato-2,2′-bipyridine)-κ3 N,N′:O-dirhenium(I) tetrahydrate, C30H22N4O18Re2

“…Yellow cuboid crystals were obtained from the mixture within three days. 3 (ReAA) was prepared as described by Alberto et al [24]. ReAA (0.1 g, 0.130 mmol) was dissolved in 20 mL water, adjusted to pH 2.2 with HNO 3 .…”

Crystal structure of fac-tricarbonyl(2-(isopropylimino)methyl-5-methylphenolatido-κ2 N,O)(pyridine-κN)rhenium(I), C19H19N2O4Re

“…+ (M = Re(I), Tc(I)) have displayed numerous attractive attributes over the past 20 odd years as precursors for the development of new radiopharmaceutical agents [1][2][3][4][5][6][7]. The three water molecules bound to the metal ion are relatively labile and can thus be easily substituted by a range of mono-, bi-, tridentate ligands and a combination thereof.…”
