(a) The molecular structure of (I), with displacement ellipsoids drawn at the 30% probability level. H atoms have been omitted for clarity. Only one position of disordered atom Cl4 is shown. (b) The rectangular 20-membered macrocycle formed by two ligands and two HgII centers. [Symmetry codes: (i) x, −y + , z; (ii) −x + 1, −y + 1, −z + 1; (iii) −x + 1, y + , −z + 1.] |
