Abstract:
The reaction of copper nitrate and triethanolamine with benzene-1,4-dicarboxylic acid (bdcH2) or 4,4'-[1,4-phenylenebis(oxy)]dibenzoic acid (podaH2) leads to the formation of poly[bis(μ4-benzene-1,4-dicarboxylato-κ4O1:O1':O4:O4)bis{μ2-[bis(2-hydroxyethyl)amino]ethanolato-κ4N,O,O',O'':κO}tricopper(II)], [Cu3(C8H4O4)2(C6H14NO3)2] or [Cu3(μ4-bdc)2(teaH2)2] (I), and poly[bis{μ4-4,4'-[1,4-phenylenebis(oxy)]dibenzoato-κ4O:O':O'':O''}bis{μ2-[bis(2-hydroxyethyl)amino]ethanolato-κ4N,O,O',O'':κO}tricopper(II)], [Cu3(C20H12O6)2(C6H14NO3)2] or [Cu3(μ4-poda)2(teaH2)2], (II). The two representative compounds contain a well-established Cu3 cluster supporting a given 44 network. The ligand length is the underlying factor that controls the degree of interpenetration. Controlled interpenetration can be facile to realise by elongating protocols. Compound I shows a non-interpenetrating 44 network, whereas II features a threefold interpenetrating network. Furthermore, similar hydrogen-bond interactions extend the different interpenetrating 44 networks into three-dimensional supramolecular topologies. Variable-temperature magnetic studies showed a ferromagnetic coupling behaviour in the two complexes.

Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
