Therefore, each L– ligand has a total coordination number of four but with different carboxylate modes, namely, κ4-N,N,O,O (1,1) in 1 and κ4-N,N,O,O′ (1,3) in 2 for the C(1)–O–C(2) group. Thus, the coordination spheres are MO2N2O in both cases, though 1 is distorted trigonal bipyramidal, whereas 2 is square pyramidal. Antiferromagnetic (AFM) coupling (17 cm–1) is seen only in 1, though the best fit was obtained
具有双(3,5-二-叔丁基吡唑-1-基)乙酸阴离子 (L– = bdtbpza) 的两种双核中心对称配位化合物,即紫色 [Co(bdtbpza)(NO3)]2 (1) 和报道了绿松石 [Cu(bdtbpza)(NO3)]2 (2)。在每个金属 (II) 离子周围,L- 配体是 κ3-N,N,O 配位的,并且 M-O 键明显长于两个 M-N 键。配位球是通过短硝基和 M-O 键与配体的结合来完成的,该配体已经与相邻的双核内金属中心 κ3-N,N,O 配位。因此,每个 L-配体的总配位数为 4,但具有不同的羧酸盐模式,即 κ4-N,N,O,O (1,1) in 1 和 κ4-N,N,O,O' (1 ,3) 在 2 中,对于 C(1)–O–C(2) 组。因此,在这两种情况下,配位球都是 MO2N2O,尽管 1 是扭曲的三角双锥体,而 2 是方锥体。反铁磁 (AFM) 耦合 (17 cm-1) 仅在
