| Summary: | Reactions of 2,2′-bipyridine-6,6′-dicarbonyl-bis(<i>N,N</i>-diethylthiourea), H<sub>2</sub>L<sup>bipy</sup>, with a mixture of thorium nitrate hydrate and nickel acetate hydrate in methanol with NEt<sub>3</sub> as a supporting base yield brown single crystals of the bimetallic complex [ThNi(L<sup>bipy</sup>)<sub>2</sub>(CH<sub>3</sub>COO)<sub>2</sub>(MeOH)]. Two 2,2′-bipyridine-centered bis(aroylthioureato) ligands connect the metal atoms in a way that the thorium atom is coordinated by two <i>O</i>,<i>N</i>,<i>N</i>,<i>O</i> donor atom sets, while the nickel atom establishes two <i>S</i>,<i>O</i> chelate rings in its equatorial coordination plane. The metal atoms are connected by a bridging acetato ligand, and their coordination spheres are completed by one methanol ligand (nickel) and a monodentate acetato ligand (thorium). A distorted octahedral coordination environment is established around the Ni<sup>2+</sup> ion, while the Th<sup>4+</sup> ion is in first approximation a 10-coordinate with a diffusely defined coordination polyhedron. |
