Abstract
The title salt [Re(2)(mu-OMe)(3)(CO)(6)](-)[DABCO-H](+) (1) was prepared as colorless prismatic crystals by the reaction of DABCO with Re(CO)(5)(OTf) in refluxing methanol solution and was characterized by spectroscopic means including single-crystal X-ray diffraction techniques. The molecular structure of 1 revealed that a novel honeycomb supramolecular architecture of the anionic organometallic complex created a cavity with an effective diameter of 7.450(3) A that houses a linear H-bonded chain of [DABCO-H](+) in its center. This structure also represents the first example of the use of a linear chain of [DABCO-H](+) species as a countercation for a coordination compound.Keywords
