[4'-(4-Amino-phen-yl)-2,2':6',2''-terpyridine]-chloridopalladium(II) chloride.

ABSTRACT: The Pd(II) atom in the complex cation of the title compound, [PdCl(C(21)H(16)N(4))]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN(3) square-planar coordination geometry. In the crystal, the presence of N-H?Cl hydrogen bonds involving the amino H atom and chloride anions link two cations and two anions into a four-ion aggregate via centrosymmetric eight-membered [?H-N-H?Cl](2) synthons. Layers of cations are inter-spersed with the chloride anions with stabilization provided by C-H?Cl inter-actions involving both Cl atoms, as well as ?-? inter-actions [the closest inter-action of 3.489?(6)?Å occurs between a chelate ring and a pyridyl residue].

Bis[4'-(4-cyano-phen-yl)-2,2':6',2''-terpyridine]cobalt(II) dichloride.

Project description:The title complex, [Co(C(22)H(14)N(4))(2)]Cl(2), has been synthesized by a solvothermal reaction of the 4'-(4-cyano-phen-yl)-2,2':6',2''-terpyridine ligand with CoCl(2)·6H(2)O. The cobalt(II) ion is six-coordinated by two tridentate ligands in a distorted octa-hedral geometry. The benzene rings form dihedral angles of 30.02?(7) and 30.26?(7)° with the mean planes of the terpyridine ring systems. The chloride anions are statistically disordered over two positions with refined site occupancies of 0.601?(2) and 0.399?(2).

4'-[2-(Trifluoro-meth-yl)phen-yl]-2,2':6',2''-terpyridine.

Project description:The title compound, C(22)H(14)F(3)N(3), is a versatile tridentate N-donor ligand consisting of a terpyridyl (terpy) molecule substituted in the 4'-position by a phenyl group, itself substituted in an ortho-position by a bulky trifluoro-methyl group. The phenyl ring is twisted as a result of steric inter-actions involving the bulky trifluoro-methyl substituent. This is reflected in the dihedral angle between the mean plane through the C atoms of the phenyl ring and the terpyridyl unit being 69.2?(1)°. The crystal structure contains no short van der Waals contacts. However, the terpy units stack in a head-to-tail orientation perpendicular to the c axis. The structure is is loosely stabilized by ?-? inter-actions between the terminal pyridine rings of adjacent mol-ecules along the stack. The perpendicular distance between the mean planes through the terpy moieties of adjacent mol-ecules is 3.4?(1)?Å.

Diethyl [4-(2,2':6',2''-terpyridine-4'-yl)phen-yl]phospho-nate.

Project description:The title compound, C25H24N3O3P, was obtained by catalytic phospho-nation of 4'-(4-bromphen-yl)-2,2':6',2''-terpyridine.

The N atoms in the two pyridine rings are oriented nearly anti-periplanar to that of the central ring. The benzene ring is rotated out of the plane of the central ring of the terpyridine unit by 34.65?(6)°.

{4'-[4-(4,4'-Bipyridin-1-ylmeth-yl)phen-yl]-2,2':6',2''-terpyridine}chloridoplatinum(II) bis-(perchlorate) acetonitrile disolvate sesquihydrate.

Project description:The asymmetric unit of the title compound, [PtCl(C(32)H(24)N(5))](ClO(4))(2)·2CH(3)CN·1.5H(2)O, comprises two unique Pt(II) complex cations, four perchlorate anions, four acetonitrile solvent mol-ecules and three water mol-ecules. The Pt atom is four-coordinated by a tridentate chelating 2,2':6',2''-terpyridine ligand and a chloride ion in a square-planar geometry with modest distortion imposed by the constraint of the terpyridyl ligand. The r.m.s. deviations from the plane comprising the four ligand donor atoms and the Pt atom are 0.0381 and 0.0472?Å in the two complex cations.

Diacetato{4'-[4-(benz-yloxy)phen-yl]-2,2':6',2''-terpyridine}zinc(II).

Project description:In the title compound, [Zn(CH(3)COO)(2)(C(28)H(21)N(3)O)], the Zn(II) ion is in a trigonal-bipyramidal ZnN(3)O(2) coordination with a tridentate N-chelating 4'-[4-(benz-yloxy)phen-yl)-2,2':6',2''-terpyridine ligand in the equatorial position and two acetate anions in the axial positions. The three pyridine rings are approximately coplanar, with a maximum deviation of 0.03?Å from the mean plane. The phen-oxy substituent makes a dihedral angle of 18.1?(2)° with the central pyridine ring. The benzyl group has a C-O-C-C torsion angle of 77.62?(8)° relative to the phen-oxy ring.

{Bis[2-(3,5-dimethyl-pyrazol-1-yl-?N)eth-yl]amine-?N}chloridopalladium(II) chloride 0.25-hydrate.

Project description:The title compound, [PdCl(C(14)H(23)N(5))]Cl·0.25H(2)O, is a pseudopolymorph of the previously reported compound [PdCl(C(14)H(23)N(5))]Cl·2H(2)O [de Mendoza et al. (2006 ?). Acta Cryst. E62, m2934-m2936]. The cationic complex and chloride anion are disordered over two positions each in a 0.584?(4):0.416?(4) ratio. The geometry about the Pd atom is distorted square-planar. The pyrazole rings are almost perpendicular, forming a dihedral angle of 86.6?(6)° to each other, to mitigate steric conflict between their methyl groups.

(2,2'-Bipyridine-κN,N')chlorido[4'-(2,5-dimethoxy-phen-yl)-2,2':6',2''-terpyridine-κN,N',N'']ruthenium(II) hexa-fluorido-phosphate acetonitrile monosolvate.

Project description:In the title compound, [RuCl(C(10)H(8)N(2))(C(23)H(19)N(3)O(2))]PF(6)·CH(3)CN, the ligand environment about the Ru(II) atom is distorted octa-hedral, with the substituted terpyridyl ligand coordinated in a meridional fashion, the bipyridyl ligand coordinated in a cis fashion and the Cl atom trans to one of the bipyridyl N atoms. The Ru-N distances are in the range 2.036 (2)-2.084 (2) Å with the exception of the central Ru-N bond from the terpyridyl ligand, which is shorter [1.9503 (19) Å], as expected. The pendant dimethoxy-phenyl substituent is not coplanar with the terpyridyl unit; the dihedral angle between the central pyridyl ring and the benzene ring is 46.72 (11)°. The anion is disordered equally over two positions around an F-P-F bond axis.
