  of the 4,4′-bpy adduct. The Rh–Rh bond distance is 2.395(1) A which is in the range of those reported for the adducts of rhodium(II) carboxylates with axial aromatic nitrogen-donor ligands. The structure of the adduct dimers, [Rh2(O2CCMe3)4(L)2] (L = tea and py), was also confirmed for a tea-coordinated complex, which has considerably long axial Rh–N (2.391(8) A) and Rh–Rh (2.413(1) A) bonds.

  新戊酸铑 (II) 与吡嗪 (pyz)、4,4'-联吡啶 (4,4'-bpy) 和 1,4-二氮杂双环 [2.2.2] 辛烷 (dabco)、三乙胺（茶）和吡啶（py）已制备。与 pyz、4,4'-bpy 和 dabco 的加合物是配制为 [Rh2(O2CCMe3)4(L)]n (L = pyz、4,4'-bpy 和 dabco) 的聚合物。通过 4,4'-bpy 加合物的 X 射线结构分析证实了具有铑 (II) 二聚体和配体交替排列的聚合物结构。Rh-Rh 键距为 2.395(1) A，这在所报道的羧酸铑 (II) 与轴向芳族氮供体配体的加合物的范围内。加合物二聚体 [Rh2(O2CCMe3)4(L)2]（L = 茶和 py）的结构也证实了茶配位的复合物，它具有相当长的轴向 Rh-N (2.391(8) A ) 和 Rh–Rh (2.413(1) A) 键。

  Properties of dirhodium catalysts with cyclometalated aryl phosphine ligands have been studied. We report here the study of the acid-base reaction of Rh-2(RCO2)(2)(PC)(2)(H2O)(2) catalysts (PC = cyclometalated aryl phosphine) with different Lewis bases. The determination of the equilibrium constants of these reactions can be used to study to which extent the properties of the axial coordination site of the catalyst, considered the active site, are affected by modification of the metalated phosphines, the carboxylate ligands, or the incoming axial ligand. The trends in the computational density functional theory interaction energies show good agreement with the major trends in the equilibrium constants, thus enabling a further study of the influence of the modification of the ligand core.
