In the title compound, [Ni(C(15)H(12)N(4))(2)](ClO(4))(2), the Ni(II) atom lies on an inversion center and is octa-hedrally coordinated by the N atoms of two tridentate tri-2-pyridyl-amine ligands. The two perchlorate anions are disordered over two sites with a refined occupancy ratio of 0.528 (19):0.472 (19).

In the title complex, [MnCl(2)(C(18)H(12)N(6))], the Mn(II) ion is five-coordinated in an approximately square-pyramidal geometry defined by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine ligand and two Cl atoms. In the crystal, the mol-ecules are stacked in columns along the c axis and display inter-molecular π-π inter-actions between the six-membered rings, the shortest ce...

In the title compound, {(C4H12N)[Mn(HCO2)3]} n , the Mn(II) atom lies on an inversion centre and is coordinated by O-atom donors from the three double-bridging formate ligands, one of which lies across a crystallographic mirror plane, giving a slightly distorted octahedral coordination sphere. A three-dimensional NaCl-type framework is generated in which the tetra-methyl-ammonium cations, which...

A series of new di-, tri-, and tetranuclear Co(II) and Cu(II) complexes of three new diSchiff base ligands were synthesized by two different methods. The first method involved the synthesis of the three ligands from condensation reaction of 3,4-dihydroxybenzaldehyde (L'H2) with ethylenediamine (en), o-phenylenediamine (o-PD), or 4,5-dimethyl-1,2-phenylendiamine (DMPD) in a mole ratio of 2 : 1 f...

BACKGROUND In the ultrasound B-mode (Brightness-mode) imaging, high side-lobe level reduces contrast to noise ratio (CNR). A linear apodization scheme by using the window function can suppress the side-lobe level while the main-lobe width is increased resulting in degraded lateral resolution. In order to reduce the side-lobe level without sacrificing the main-lobe width, a non-linear apodizatio...

Reaction of [Ln(I)3(THF)4] (Ln = Ce, Pr) or [Ln(I)3(THF)3.5] (Ln = Nd, Sm, Gd, Dy, Er) with three equivalents of [KBz] (Bz = CH2C6H5) at 0 degrees C afforded the corresponding lanthanide tri-benzyl complexes [Ln(Bz)3(THF)3] [Ln = Ce (2), Pr (3), Nd (4), Sm (5), Gd (6), Dy (7), Er (8) La (11)] in 48-75% crystalline yields, with the exception of the redox active samarium complex, which was isolat...

In the crystal structure of the title compound, [CoK(CHO2)3]n the Co cations are coordinated by six O-bonded formate anions in an octahedral coordination mode and the K cations are eightfold coordinated by seven O-bonded formate anions within irregular polyhedra. The Co cations are connected by bridging formate anions into a three-dimensional coordination network in which the K cations are embe...

In the title compound, [Pd(CF3)(C6H4F)(C6H16N2)], the Pd(II) cation is four-coordinated by the two N atoms of the N,N,N',N'-tetra-methyl-ethylenedi-amine ligand and by one C atom each from a 4-fluoro-phenyl and a tri-fluoro-methyl ligand, in a distorted rectangular-planar geometry, with an average deviation from the least-squares plane of 0.066 (2) Å. The central coordination angles with the Pd...
