In the title mononuclear copper(II) complex, [Cu(C(7)H(5)ClNO)(2)], the Cu atom, situated on an inversion center, is four-coordinated, in a slightly distorted square-planar geometry, by the N- and O-donor atoms of two symmetry-related 4-chloro-2-(imino-meth-yl)phenolate Schiff base ligands.

In the title complex, [Ni(C(11)H(9)ClN(3)O(2))(2)]·4H(2)O, the Ni atom is coordinated by four N atoms and two O atoms derived from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The cis-N(4)O(2) donor set defines a distorted octa-hedral geometry. In the crystal structure, the complex and water mol-ecules are linked by O-H⋯O hydrogen bonds.

Single-molecule magnets are a type of coordination compound that can retain magnetic information at low temperatures. Single-molecule magnets based on lanthanides have accounted for many important advances, including systems with very large energy barriers to reversal of the magnetization, and a di-terbium complex that displays magnetic hysteresis up to 14 K and shows strong coercivity. Ligand ...

To determine the trans effect on the rates of reductive eliminations from arylpalladium(II) amido complexes, the reactions of arylpalladium amido complexes bearing symmetrical and unsymmetrical DPPF (DPPF = bis(diphenylphosphino)ferrocene) derivatives were studied. THF solutions of LPd(Ar)(NMeAr') (L = DPPF, DPPF-OMe, DPPF-CF3, DPPF-OMe,Ph, DPPF-Ph,CF3, and DPPF-OMe,CF3; Ar = C6H4-4-CF3; Ar' = ...

The asymmetric unit of the title complex, [Pd(C15H13FNO)2], contains one half of the mol-ecule with the Pd(II) cation lying on an inversion centre and is coordinated by the bidentate Schiff base anion. The geometry around the cationic Pd(II) centre 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...

In the title compound, [Cd(C(8)H(7)O(3))(2)(C(12)H(8)N(2))(2)]·5H(2)O, the Cd(II) ion is six-coordinated by two carboxylate O atoms of monodentate 2-(4-hy-droxy-phen-yl)acetate ligands and by four N atoms from two chelating 1,10-phenantroline ligands in a distorted trigonal-prismatic geometry. O-H⋯O hydrogen bonds between water mol-ecules and the complex mol-ecules result in the formation of a ...

The asymmetric unit of the title complex, [Ni(C14H11FNO)2], contains one-half of the mol-ecule with the Ni(II) cation lying on an inversion centre coordinated by a bidentate Schiff base anion. The cationic Ni(II) center is in a distorted square-planar coordination environment 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 l...
