Abstract:
Calix[4]arenes are excellent ligand supports for the synthesis of polymetallic clusters of transition and lanthanide metal ions, as well as 3d-4f ion mixtures. Bis-calix[4]arene, a recent addition to the calixarene family, forms structurally related cages that mirror the metal ion binding preferences of calix[4]arene. Here we show that stoichiometric control causes remarkable expansion in the cores of two known bis-calix[4]arene-supported clusters, with concomitant changes to the magnetic properties observed.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
¹H NMR: Long-Range Coupling
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene...
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
