Yh. Chen et al., A linear metal string [Cr-7(mu(7)-teptra)(4)Cl-2] complex with delocalizedheptachromium(II) multiple bonds (teptraH(3) = tetrapyridyltriamine), CHEM COMMUN, (17), 1999, pp. 1667-1668
A heptachromium(II) metal chain helically wrapped by four all-syn type tept
ra(3-) ligands with delocalized Cr-II-Cr-II-Cr-II-Cr-II-Cr-II-Cr-II-Cr-II m
ultiple bonds is found in the complex [Cr-7(mu(7)-teptra)(4)Cl-2]. The band
structure of a hypothetical one-dimensional chromium string based on this
structure is calculated and shows metallic behavior for the string structur
