Abstract
Mercury(II) complexes of selones (L) having the general formulae, [L
2HgCl
2], [L
3HgCl]Cl and [L
4Hg]Cl
2 have been prepared and characterized by elemental analysis, IR and NMR (
1H,
13C,
15N,
77Se,
199Hg) spectroscopy. The complex of dichloro-bis(
N-
isopropyl-imidazolidine-2-selone-S)mercury(II), has been characterized by X-ray crystal analysis. The principal components of the
77Se and
199Hg shielding tensors were determined from solid-state NMR data.

C
Se mode upon complexation is indicative of mercury(II) binding via a selone group. Upfield shifts in
C
Se resonance of selones in
13C and
77Se NMR and downfield shifts in N
H resonances in
1H and
15N NMR are consistent with the selenium coordination to mercury(II). The complex of dichloro-bis(
