合成了10个[Rh_2(O_2CMe)_4]与含氮配体的加合物:[Rh_2(O_2CMe)_4L_2),L=哌啶,4-氨基安替比林,3-氨基苯二甲酰环肼(鲁米诺),2,5-二苯基噁唑(PPO),1,4-二(2-(5-苯基噁唑基)]苯(POPOP);[Rh_2(O_2CMe)_4L_2]·H_2O,L=苯骈噻唑,1-萘胺;[Rh_2(O_2CMe)_4L]_n,L=外消旋—5,7,7,12,12,14-六甲基—1,4,8,11-四氮杂环十四烷(tet b),4,4′-二胺基-3,3′-二甲基联苯(邻联甲苯胺)。研究了它们的红外光谱,测定了它们在乙醇—苯中的稳定常数,观察到logβ_2与加合物电子光谱谱带I的波数v_1呈正相关关系。讨论了π相互作用对轴向Rh-L成键的贡献。
10 adducts of [Rh_2 (O_2CMe) _4] and nitrogen-containing ligands were synthesized: [Rh_2 (O_2CMe) _4L_2), L = piperidine, 4-aminoantipyrine, 3- aminophthaloyl ring Hydrazine, 2-diphenyloxazole (PPO), 1,4-bis (2- (5-phenyloxazolyl) · H_2O, L = benzothiazole, 1-naphthylamine; [Rh_2 (O_2CMe) _4L] _n, L = rac-5,7,7,12,12,14-hexamethyl-1,4,8 , 11-tetrabicyclotetradecane (tet b), 4,4’-diamino-3,3’-dimethylbiphenylene (o-tolidine) .The infrared spectra of them were studied, Their stable constants in ethanol-benzene were observed to have a positive correlation between the log β 2 and the wavenumber v_1 of the adduct electron spectral band I. The contribution of the π interaction to the axial Rh-L bond formation was discussed.
