该通讯报道了含有 RNNNNNNR(2-) 配体的过渡金属配合物的第一个例子。将 1-叠氮金刚烷添加到二铁 (I) 合成子 L(R)FeNNFeL(R) (L(R) = HC[C(R)N(2,6-iPr(2)C(6)H(3))](2)；R 甲基、叔丁基) 得到二铁配合物L(R)Fe(mu-eta(2):eta(2)-AdN(6)Ad)FeL(R)，具有令人惊讶的热稳定性。磁性、穆斯堡尔和晶体学数据与通过双阴离子 AdN(6)Ad(2-) 桥反铁磁耦合的高自旋铁 (II) 离子对一致。
This communication reports the first examples of transition metal complexes containing an RNNNNNNR(2-) ligand. Addition of 1-azidoadamantane to the diiron(l) synthon L(R)FeNNFeL(R) (L(R) = HC[C(R)N(2,6-iPr(2)C(6)H(3))](2); R methyl, tert-butyl) leads to the diiron complexes L(R)Fe(mu-eta(2):eta(2)-AdN(6)Ad)FeL(R), which are surprisingly thermally stable. Magnetic, Mossbauer, and crystallographic data are consistent with pairs of high-spin iron(II) ions antiferromagnetically coupled through a dianionic AdN(6)Ad(2-) bridge.
