Popis:	We determined the199mHg nuclear quadrupole interaction (NQI) by time differential perturbed angular correlation in the following ferrocenethiol complexes with mercury: ferrocenethiol (vQ=1253(4) MHz, η=0); 1,1′-ferrocenedithiol (47%vQ=1555(8) MHz, η=0.13(2); 25%vQ=726(19) MHz, η=0.81(2); rest unspecific); 2-ferrocenyl-ethanethiol (vQ=1306(6) MHz, η=0.17(1)); and a 1, 1′-bis (2-mercapto-propylthio)ferrocene oligomer (vQ=1411(5), η=0). All NQIs are rather large with small asymmetry parameters, indicating essentially linear S-Hg-S bonds. The only exception is the minority fraction in 1,2′-ferrocenedithiol which suggests the formation of a 1,3-dithia-2-mercura[3]ferrocenophane.
