Beyond Charge Density Matching: The Role of C–H···O Interactions in the Formation of Templated Vanadium Tellurites

A hierarchy of influences in the formation of templated vanadium tellurites is described and discussed in the context of two new compounds. Three Haverford undergraduates appears as co-authors. --author-supplied description

Inducing polarity in [VO3]nn- chain compounds using asymmetric hydrogen-bonding networks

One centrosymmetric and a pair of polar noncentrosymmetric templated metavanadates were synthesized under mild hydrothermal conditions. Asymmetry in the hydrogen-bonding between either [(R)-C5H14N2]2+ or [(S)-C5H14N2]2+ and [VO3]nn- chains results in polar structures that exhibit type 1 phase-matching capabilities. Hirshfeld surfaces were used to probe the hydrogen-bonding networks and component and net dipole moments were calculated from atomic positions and iterative-Hirshfeld partial charges. --author-supplied descriptio
