摘要:
The complexes trans-[FeI2(CN-3-pyridyl)(4)], trans-[PdI2(CNR)(2)] (CNR = 2-, 3-and 4-isocyanopyridine, 3-isocyanoquinoline, 4-isocyanoquinaldine, 5-isocyanoquinoline, 5-isocyanoisoquinoline) and trans-[PtI2(CNR)(2)] (CNR = 3-isocyanopyridine, 5-isocyanoquinoline) were prepared. The new complexes are thermally stable up to 150 degrees C or higher. The molecular structure of trans-[PdI2(CN-3-quinolyl)(2)] was determined by X-ray crystallography: monoclinic space group P2(1)/c, a = 5.8381(5), b = 23.685(2), c = 7.2122(6) Angstrom, beta = 97.628(8)degrees, Z = 2, 1170 unique reflections, R = 0.035, R-w = 0.035. In the crystal, the molecular units are packed to form two-dimensional sheets which are held together by pi stacking of the 3-quinolyl groups.
