Abstract:
The crystal structure of the title dimolybdenum complex, [Mo(2)(C(12)H(9)NO)(C(7)H(7)O(2))(2)(CO)(4)], has a quasi-tetra-hedral Mo(2)C(2) cluster core attached to one 3-(8-quinol-yloxy)propanediyl (L) and two methoxy-carbonyl-cyclo-penta-dienyl (Cp') ligands which are coordinated to two Mo atoms: one Mo atom bonds two terminal CO ligands while the other links one terminal and one semi-bridging CO ligand. An intra-molecular C-H⋯N hydrogen bond results in the quinolyl plane of the L ligand approaching and being nearly perpendicular to one of the Cp' rings [88.09 (12)°]. In the supra-molecular structure, a one-dimensional comb-shaped infinite chain is formed approximately along the crystallographic c axis by a combination of inter-molecular C-H⋯O hydrogen bonds and locally generates a C(6) motif. Finally, pairs of inversion-related comb-shaped chains associate into a new ladder-shaped infinite chain through weak π-π stacking inter-actions between neighbouring quinolyl systems (pyridyl centroid-centroid distance = 3.853 Å).

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
