Anionic Ligands

In the crystal structure of the title compound, [Ni(C2N3)2(C5H5N)4], the NiII cations are coordinated by four pyridine ligands and two dicyanamide anions into discrete complexes. The shortest Ni...Ni separation is 8.1068 (10) Å. The structure is pseudo-centrosymmetric and can also be refined in the space group C2/c in which both anionic ligands are strongly disordered and the refinement leads to significantly poorer reliability factors.

The reaction in methanol of CuII acetate monohydrate with 5-fluoroisatin 3-oxime deprotonated with KOH in a 1:2 molar ratio and recrystallization from pyridine yielded the title compound, [Cu(C8H4FN2O2)2(C5H5N)2]. In the centrosymmetric complex, the anionic form of the isatin oxime acts as a κ2 N,O donor, building five-membered metallarings. The CuII cation is sixfold coordinated in a slightly distorted octahedral environment by two trans, equatorial, anionic isatin derivatives and two trans pyridine ligands in axial positions. The complexes are linked by hydrogen bonding into a three-dimensional network, which is also stabilized by π–π stacking interactions [centroid-to-centroid distance = 3.7352 (9) Å] and C—H...π contacts. The Hirshfeld surface analysis indicates that the major contributions for the crystal packing are H...H (31.80%), H...C (24.30%), H...O (15.20%) and H...F (10.80%). This work is the second report in the literature of a crystal structure of a coordination compound with isatin 3-oxime ligands (coordination chemistry).

The Mean

The title compound, C22H15N3O2, can be described as a ketone with a phenol substituent and a terpyridine ligand coordinated to the carbonyl group. The three six-membered rings of the terpyridine ligand are not coplanar. The dihedral angles between the mean planes of the central ring and the external pyridine ligands are 22.77 (9) and 26.77 (7)°. The central ring of the terpyridine ligand is also not coplanar with the o-hydroxy phenyl ring, the dihedral angle being 39.72 (5)°. An intramolecular O—H...O hydrogen bond occurs. The crystal structure of the title compound is consolidated by C—H...O and C—H...N hydrogen bonding interactions.

Platinum antitumour agents, containing aromatic rings, which are used for targeting DNA in effective therapies for the treatment of cancer. We have synthesized the title metallocomplex with an aromatic ligand and determined its crystal structure. In many cases, complexes of platinum and other metals have a symmetrical structure. In contrast, the platinum(II) complex with pyridine and N-(9-anthracenylmethyl)-1,2-ethanediamine as ligands (systematic name: cis-{N-[(anthracen-9-yl)methyl]ethane-1,2-diamine-κ2 N,N′}bis(pyridine-κN)platinum(II) dinitrate), [Pt(C5H5N)2(C17H18N2)](NO3)2, is asymmetric. Of the two pyridine ligands, only one is π-stacked with anthracene, resulting in an asymmetric structure. Moreover, the angle of orientation of each pyridine ligand is variable. Further examination of the packing motif confirms an intermolecular edge-to-face interaction.
