摘要：

Se-77-n.m.r. chemical shifts of metal(II)- and metal(III)-bis-chelates of 1,3-diselenole-2-selone-4,5-diselenolate (dsis), 1,3-dithiole-2-selone-4,5-diselenolate (dsise), 1,3-dithiole-2-selone-4,5-dithiolate (dmise) and 1,3-dithiole-2-thione-4,5-diselenolate (dsit) and relaxation times T1 (spin-lattice relaxation time) of the Se nucleus of (Bu4N)2[Zn(dsit)2], (Bu4N)2[Zn(dmise)2] and (Bu4N)2[Zn(dsise)2] are reported. Comparisons are made between Se-77-n.m.r. chemical shifts and the nature of coordination centre and coordination geometry.
