 Title    Schwingungsspektren und Kraftkonstanten von linearen  
 Abstract    Anionen [MnP2]4' und [M!X2]5-(M11 = Zn, Cd, Hg; M1 = Cu, Ag; X = E15) in den Kaliumverbindungen und in Na4[HgP2] V ibrational S pectra and Force C onstants of the L inear A nions [M n P2]4-and [M IX 2]5" (M 11 = Z n, Cd, Hg; M 1 -Cu, Ag; X -E 15) in Potassium C om pounds and in N a4[H gP2] M eh m et S om er The vibrational spectra of the title compounds have been recorded and interpreted based on the symmetry o f the isolated linear anions [M X2]"~ (M = Cu, Ag, Zn, Cd. Hg; X = P, As, Sb). The calculated stretching force constants are: f(M n -P) = 1.89 {M11 = Zn}, 1.66 {Cd}, 1.83 {Hg} N cm -1 and f(C u -X) = 1.27 {X = P}, 0.99 {Sb} and f(A g -A s) = 0.93 N c m " 1 respectively. These are compared with those of the isoelectronic m olecules M nY 2 and [M'Y2]~ in relation to charge effects (M 11 = Zn, Cd, Hg; M 1 = Cu, Ag; Y = Cl, Br).
