cis,trans-Dicarbonyldichlorido(1,10-phenanthroline-5,6-dione-κ²N,N′)ruthenium(II)

Abstract

In the title compound, [RuCl2(C12H6N2O2)(CO)2], the RuIIatom (site symmetry ..2) adopts a distorted octahedral coordination sphere defined by two carbonyl C atoms, two Cl−anions and two N atoms from the chelating 1,10-phenanthroline-5,6-dione (phendione) ligand. The carbonyl ligands arecisto each other, while the Cl atoms aretrans. In the phendione ligand, the C=O [1.239 (5) Å] and the C—C [1.537 (5) Å] bond lengths in the diketone moiety have typical values. In the crystal, C—H...Cl and C—H...O hydrogen bonds lead to the formation of a three-dimensional supramolecular network.

“…In the obtained molecular structure, the substituted OH 2 ligand is coordinated trans to one of the CO ligands, the pyridine ring of pynp is coordinated trans to the other CO ligand, and the naphthyridine ring system of pynp is coordinated trans to the Cl ligand. The bond parameters of the Ru-CO Ru-Cl, and Ru-O moieties are comparable to those of similar ruthenium(II) complexes (Table 1) [7,[9][10][11]. Of the two Ru-N bond lengths, the one involving the pyridine N atom is longer (2.128(4) vs. 2.074(4) Å) because of the trans effect of the carbonyl group.…”
