%X The nature of the molybdenum-mercury bond has been studied by means of i.r. and multinuclear n.m.r. spectroscopies on complexes of the type (&#951;5-C5H5)(CO)2LMoHgX [L = CO, P(OMe)3 and PPh3; X = Cl, Br, I, S2COEt, S2P(OEt)2, S2CNEt2 and Mo(CO)3(&#951;5-C5H5)]. The results indicate the strong covalent character of the Mo-Hg bond. The chemical shifts of 95Mo resonances were found in the range from -1706 to -1939 ppm and those of 199Hg ones in the range from +236 to -1107 ppm. The structure of (&#951;5-C5H5)(CO)3MoHgS2CNEt2 has been determined; P21/2, a 12.012(5), b 8.206(3), c 17.037(4) Å, &#946; 92.58(3)º, Z 4, R 0.045. Mo-Hg distance is 2.714(3) Å.
