Abstract:
Two unique heterometallic cluster organic frameworks, [Cd4 MnIII 4 MnII 6 (Tri)4 (CH3 COO)14 (μ4 -O)2 (μ3 -O)2 (H2 O)2 ] Cd(H2 O)2 ⋅9 H2 O (1) and Cu[Cd5 Cu6 (Tri)4 (CH3 COO)9 (H2 O)4 ]2 (CH3 COO)3 ⋅24 H2 O (2) (H3 Tri=2-(hydroxymethyl)-2-(pyridine-4-yl)-1,3-propanediol), have been successfully prepared by employing a bifunctional tripodal alcohol ligand as a structure-directing agent. Crystal structure analyses reveal that 1 represents a rare example of frameworks constructed from Cd-Mn heterometallic chains, and 2 is the first heterometallic MOF based on highest-nuclear Cd-Cu heterometallic cluster building blocks. Furthermore, the magnetic properties and gas adsorption abilities of 1 and 2 were systematically studied.

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.
