In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Crystal and molecular structure of the complex boron triferrocenyl-pyridine, published in 1987-12-31, which mentions a compound: 1273-73-0, mainly applied to crystal structure trisferrocenylboron pyridine complex; mol structure trisferrocenylboron pyridine complex; ferrocenylboron pyridine complex structure, COA of Formula: C10BrFe.
X-ray study of the title tris(ferrocenyl)boron pyridine complex confirms that in the solid state its structure is similar to that inferred from chem. and spectroscopic evidence. The B atom is coordinated by 3 ferrocenyl groups and a pyridine ring in a distorted tetrahedral array. The mol. has a nearly 3-fold axis normal to the plane defined by the ferrocenyl groups. The B-N distance of 1.656 (5) Å is larger than that obtained for other compounds studied. The pyridine and cyclopentadienyl rings are planar. The H atoms of the cyclopentaidenyl rings are displaced significantly toward their corresponding Fe atom. The mols. in the crystal are packed at normal van der Waals distances. No unusually short intermol. contacts are noted.
In addition to the literature in the link below, there is a lot of literature about this compound(Bromoferrocene)COA of Formula: C10BrFe, illustrating the importance and wide applicability of this compound(1273-73-0).
