The asymmetric unit of the title complex, [Pd(C15H13FNO)2], contains one half of the molecule with the PdIIcation lying on an inversion centre and is coordinated by the bidentate Schiff base anion. The geometry around the cationic PdIIcentre is distorted square planar, chelated by the imine N- and phenolate O-donor atoms of the two Schiff base ligands. The N- and O-donor atoms of the two ligands are mutuallytrans, with Pd—N and Pd—O bond lengths of 2.028 (2) and 1.9770 (18) Å, respectively. The fluorophenyl ring is tilted away from the coordination plane and makes a dihedral angle of 66.2 (2)° with the phenolate ring. In the crystal, molecules are linked into chains along the [101] direction by weak C—H...O hydrogen bonds. Weak π–π interactions with centroid–centroid distances of 4.079 (2) Å stack the molecules alongc.

Ring Motif

In the title complex, [Hg(NCS)2(CH4N2S)2], the HgIIatom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thiocyanate groups and two thiourea groups. The S—Hg—S angles are 172.02 (9)° for thetrans-thiocyanate S atoms and 90.14 (5)° for thecis-thiourea S atoms. The molecular structure is stabilized by an intramolecular N—H...S hydrogen bond, which forms anS(6) ring motif. In the crystal, molecules are linked by a number of N—H...N and N—H...S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966).Rocz. Chem.40, 547–569] with an extremely highRfactor of 17.2%, and no mention of how the data were collected.

The molecular structure of the title complex, [Ni(C13H8F2N2O)(C14H32P2)] or Ni(oFPU)(dippe), where oFPU is the dianion of bis(2-fluorophenyl)urea and dippe is 1,2-bis(di-isopropylphosphino)ethane, comprises an NiII atom with a distorted square-planar coordination environment (geometry index τ4 = 0.195). One of the fluorophenyl rings of the oFPU ligand is disordered over two sets of sites in an 0.832 (7):0.168 (7) ratio. The crystal structure displays C—H...O and C—H...F hydrogen-bonding interactions, leading to chains with R 2 2(12) motifs extending parallel to [100]. The title compound might be of interest with respect to the production of urea and carbamate derivatives of nickel(II).

The square-planar nickel(II) title complex, [Ni(C24H36F2N6)](ClO4)2 or [NiL](ClO4)2 (L = 3,10-bis(4-fluorophenethyl)-1,3,5,8,10,12-hexaazacyclotetradecane) was synthesized by a one-pot reaction of template condensation and its X-ray crystal structure was determined. The nickel(II) ion lies close by a twofold axis and the complex displays whole-molecule disorder. Ligand L, a hexaazacyclotetradecane ring having 4-fluorophenethyl side chains attached to uncoordinated nitrogen atoms, adopts a trans III (R,R,S,S) configuration. The average Ni—N bond distance is 1.934 (9) Å, which is quite similar to those of other nickel(II) complexes with similar ligands. The nickel(II) ion is located 0.051 (7) Å above the least-squares plane through the four coordinated N atoms. The average C—N bond distance and C—N—C angle involving uncoordinated nitrogen atoms are 1.425 (12) Å and 118.0 (9)°, respectively, indicating a significant contribution of sp 2 hybridization for these N atoms. The intermolecular N—H...O, C—H...O/F hydrogen bonds of the complex form a network structure, which looks like a seamless floral lace pattern.

The crystal structure of the organoplatinum(II) title complex, [Pt(C9H6NO)(C11H13O2)] or [Pt(methyleugenol)(8-hydroxyquinolinato)], has been determined in order to verify the coordination environment of the PtIIcation, which was found to be square-planar with the N and O atoms of the quinolinate ligandcisandtrans, respectively, with respect to the ethylenic double bond. The least-squares planes through the two aromatic ring systems make an angle of 39.87 (10)°. In the crystal, chains are formed parallel to [100] sustained by C—H...O hydrogen bonds. Parallel chains further interactviaC—H...O and C—H...π contacts. The complex shows interesting activity on four human cancer cell lines with IC50values between 1.92 and 4.86 µM.
