✦ Synopsis
vibration, which appears with high intensities for other Hgl derivatives, could not be detected in the Raman spectrum of this compound"091. In the meantime, further Hg' derivatives of bis(fluor0sulfonyl)amine, N,N-bis(fluorosulfonyI)urea, and fluorosulfonylcarbamates have been prepared r1101 and investigated by vibrational spectrometric methods alongwith mercury(1) diacetohydrazide. All compounds exhibit intense Raman lines caused by Hg-Hg vibrations. From the observed frequencies Hg-Hg [lo91 H . Stammreich and T .
