The 31P{1H}-NMR characteristics of the complexes [HgX2(1)] and [HgX2-(PPh2Bz)2] (X = NO3, Cl, Br, I, SCN, CN) and the solid state structures of the complexes [HgCl2(1)] and [HgI2(1)] (1 = 2,11-bis (diphenylphosphinomethyl)benzo-[c]phenanthrene) have been determined.The 1J(199Hg, 31P) values increase in the order CN 〈 I 〈 SCN 〈 Br 〈 Cl 〈 NO3. The two molecular structures show a distorted tetrahedral geometry about mercury. Pertinent bond lengths and bond angles from the X-ray analysis are as follows: Hg—P = 2.485(7) Å and 2.509 (8) Å, Hg—Cl = 2.525 (8) Å and 2.505 (10) Å, P—Hg—P = 125.6(3)°, Cl—Hg—Cl = 97.0(3)° for [HgCl2(1)] and Hg—P = 2.491 (10) Å and 2.500(11) Å, Hg—I = 2.858(5) Å and 2.832(3) Å, P—Hg—P = 146.0(4)°, I—Hg—I = 116.9(1)° for [HgI2(1)]. The equation, derived previously, relating 1J(199Hg, 31P) and the angles P—Hg—P and X—Hg—X is shown to be valid for 1.
