T. Kawamoto et Y. Kushi, THE EFFECT OF AROMATIC-AROMATIC INTERACTIONS ON THE CRYSTALLIZATION OF HELICAL NICKEL(II) COMPLEXES, Inorganica Chimica Acta, 282(1), 1998, pp. 71-75
Five monometallic helical nickel(II) complexes, with various substitue
nts on the pendant arms, were prepared. The crystal structures of thre
e complexes consist of alternating right- and left-handed helical comp
lexes, with intermolecular face-to-face interactions. On the other han
d, the other two complexes crystallize in right-handed or left-handed
molecules alone, with intermolecular edge-to-face interactions. This b
ehaviour can be correlated with the electron-releasing properties of t
he substituents on the pendant arms. (C) 1998 Elsevier Science S.A. Al
