Hydrogenation Reactions

The title compound, [Ir2(C14H19N3)2(C8H12)2(C28H28P2)](BF4)2·2CH2Cl2, has triclinic (P-1) symmetry and the dication lies about an inversion center located at the mid-point of the butane chain of the phosphine ligand. The IrI ion has a distorted square-planar coordination geometry. The N-heterocyclic carbene ligand has an extended S-shaped conformation. The diphosphine ligand acts as a bridge between the two metal centers. This is the first structural report of a complex where the square-planar iridium centers are bridged by a phosphine ligand, and it is of interest with respect to catalysis in transfer hydrogenation reactions. Parts of the triazole and cyclooctadiene ligands and the tetrafluoroborate anion are disordered over two sets of sites.

The title compound, [Pd(C11H8N)(C6H10NS2)], crystallizes with three similar and discrete molecules in the asymmetric unit. The CNS2donor set defines a distorted square-planar geometry around the PdIIatom, with very small deviations from planarity. The bidentate nature of the ligands gives fairly large deviations from the ideal 90° angles; the C—Pd—N angles are all around 81° and the S—Pd—S angles are around 75°. Molecules packviadispersion interactions.

The Mn2+ion in (I) is coordinated by twoO,O′-bidentate Hspar neutral molecules (which exist as zwitterions) and anO,O′-bidentate bdc dianion to generate a distorted MnO6trigonal prism. A very long bond [2.580 (12) Å] from the Mn2+ion to a 0.25-occupied water molecule projects through a square face of the prism. In (II), the Cu2+ion lies on a crystallographic inversion centre and a CuO4square-planar geometry arises from its coordination by twoO,O′-bidentate Hspar molecules. The bdc dianion acts as a counter-ion to the cationic complex and does not bond to the metal ion. The Hspar ligands in both (I) and (II) feature intramolecular N—H...O hydrogen bonds, which closeS(6) rings. In the crystals of both (I) and (II), the components are linked by N—H...O, O—H...O and C—H...O hydrogen bonds, generating three-dimensional networks.
