摘要:
Two neutral nickel complexes of multi-sulfur 1,2-dithiolenes, [Ni(MEDT)(2)], 1 (MEDT = 5,6-dihydro-5-methyl-1,4-dithiin-2,3-dithiolate), and [Ni(PHDT)(2)], 2 (PHDT = 5,6-dihydro-5-phenyl-1,4-dithiin-2,3-dithiolate) have been prepared and characterized. The X-ray structure analysis of 1 reveals that the molecules are arranged as two different oriented ''stacks'' along the a axis. The shortest intrastack S ... S contact is 3.9312 Angstrom.
