Potential constants of K$sub 2$Zn(CN)$sub 4$ in the crystal lattice
The vibrational spectra of the crystalline materials K$sub 2$Zn(CN)$sub 4$, K$sub 2$Zn($sup 13$CN)$sub 4$, K$sub 2$Zn(C $sup 15$N)$sub 4$, K$sub 2$ $sup 64$Zn(CN)$sub 4$, and K$sub 2$ $sup 68$Zn(CN)$sub 4$ have been observed using infrared and Raman spectroscopy. A number of the potential constants in this system have been calculated from the various isotopic frequencies. It was necessary to constrain several of the potential constants which are essentially indeterminate. An analysis of these constraints was made to show that they are justified. A comparison of the potential constants of Zn(CN)$sup -2$$sub 4$ with isoelectronic Ni(CO)$sub 4$ shows that for the zinc complex there is negligible back-$pi$ bonding of the zinc d orbitals to the CN ligands. A number of interesting stretch--stretch and stretch--bend interactions are discussed. (AIP)
