Hydrogen out-of-plane bending in cyclopentadienyllithium

Hydrogen out-of-plane bending in cyclopentadienyllithium. Waterman, Kenneth C.; Streitwieser, Andrew, Jr. (Dep. 16733-97-4 are also occured in this study. Chem., Univ. California, Berkeley, CA 94720, USA). J. Am. Chem. Soc., 106(11), 3138-40 (English) 1984. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 An ab initio SCF MO study is presented for the out-of-plane bending of H atoms in cyclopentadienyllithium. The effects of basis sets of varying size and possible superposition errors were evaluated. The H atoms bend away from the Li cation to a significant degree. Comparable bending is given by an ionic model consisting of a cyclopentadienyl anion and a point pos. charge was attributed to a simple Coulombic effect: such bending puts more neg. charge on the face of the ring towards the Li cation. No covalency is implicated in this effect. A reasonable balance between the C and Li bases is obtained by placing a diffuse sp shell on C. .
