title: Synthesis and structural studies of 1,1'-bis-amino-functionalized ferrocenes, ferrocene salts, and ferrocenium salts.
abstract: Having isolated and characterized a series of sodium cyclopentadienide salts, we have synthesized a number of 1,1'-bis-amino-functionalized ferrocenes, 1,1'-bis-amino-functionalized ferrocene salts, and 1,1'-bis-amino-functionalized ferrocenium salts. Among these are the first crystallographically characterized examples of cyclopentadienyl units containing (piperidin-N-ylethyl)- and (pyrid-2-ylmethyl)cyclopentadienyl side chains. In the cases of some of the ferrocenes, ferrocene salts, and ferrocenium salts, there are some interesting structural features in the solid state. These include C-H...N and C-H...pi cloud interactions as well as N-H...O and N-H...F hydrogen bonds.
