草酸根配合物

草酸根配合物是含有草酸根（C₂O₄²⁻）配體的配合物。草酸根是一种双齿配体。[1]作为一种小的对称双阴离子，草酸根通常会形成MO₂C₂五元环。草酸根配合物中也可以有其它配体，例如 [Co(C₂O₄)(NH₃)₄]^κ+。[2]

一些草酸根配合物的结构

[Cr₂(oxalate)₅]^4-
草酸铁钾（K
3[Fe(C
2O
4)
3] · 3H₂O）
抗癌药物奥沙利铂
[Zr(oxalate)₄]^4-

均配物

草酸根配合物中很多都只含草酸根，它们的通式为 [M(κ²-C₂O₄)₃]^n-，其中M = V(III)、Mn(III)、[3]Cr(III)、Tc(IV)、Fe(III)、Ru(III)、Co(III)、Rh(III)和Ir(III)。这些阴离子有手性（D₃对称性），有些对映异构体可以分离。[4]一些金属也可以形成有四个草酸根的配合物 [M(κ²-C₂O₄)₄]^n-，其中 M = Nb(V)、[5]Zr(IV)、[6]Hf(IV)[7]和Ta(V)。[8]

双金属配合物

草酸根也可以作为一种桥接配体，形成含有 (κ²,κ'²-C₂O₄)M₂核心的双核或多核配合物。双核草酸根配合物的通式为 [M₂(C₂O₄)₅]^n-，其中 M = Fe(II)[9]和Cr(III)[10]。
