Electric Multipole Moments and (Hyper)Polarizability of X–C≡C–X, X = F, Cl, Br and I

Electric Properties of Molecule Zr₂Fe Based on the Full Relativistic Theory

The present work is devoted to the study of the electric properties: electric dipole moment, electric quadrupole moment, electric field gradients and electric dipole polarizability of molecule Zr₂Fe on base of the full relativistic theory with basis set 3–21G. The electric dipole moment of Zr₂Fe is symmetrical to the axis of C2V—the vector sum of two projections for two chemical bond FeZr (3.2883 Å), based on when there is charge distribution. The force constant k2 is directly connected with electric field gradients.

Complicated synergistic effects between metal–π interaction and halogen bonding involving MCCX

Complicated synergistic effects have been found between metal–π interaction and halogen bond in the complexes FCCF⋯MCCX⋯NCH (M = Li, Cu, Ag, and Au; X = Cl, Br, and I).
