In the title compound, Na(3)(C(6)H(15)N(5)O)(2)[Al(OH)(6)Mo(6)O(18)](2)Cl·20H(2)O, the [Al(OH)(6)Mo(6)O(18)](3-) polyoxo-anion has a B-type Anderson structure exhibiting approximate D(3d) symmetry. There are two types of sodium cations: the Na(+) cations of type I have a distorted octa-hedral coordination geometry formed by six O atoms and are statistically distributed over two positions with e...
The title compound, CH(7)N(4) (+)·C(4)H(5)O(4) (-), is a molecular salt containing discrete amino-guanidinium and succinate ions. The amino-guanidinium cation is nearly planar, with a maximum deviation of 0.035 (1) Å. The dihedral angle between the amino-guanidinium cation and the succinate anion is 3.35 (6)°. The crystal packing exhibits inter-molecular N-H⋯O and O-H⋯·O hydrogen bonds.
The formation of like-charge guanidinium-guanidinium contact ion pairs in water is evidenced and characterized by X-ray absorption spectroscopy and first-principles spectral simulations based on molecular dynamics sampling. Observed concentration-induced nitrogen K-edge resonance shifts result from π* state mixing and the release of water molecules from each first solvation sphere as two solvat...
We report the synthesis of guanidinium-functionalized cationic dendrons with pendant alkyl chains varying lengths, which are classified as antibacterial molecular umbrellas.
