The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu⋯Cu separation of 6.136 (16) Å. The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43 Å) Cu⋯O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Using a highly effective binuclear Cu complex as the catalyst, the 1,3-dipolar cycloaddition reactions between 16 alkynes and two azides were successfully performed and resulted in the production of 25 new triazole-containing sorafenib analogs. Several compounds were evaluated as potent antitumor agents. Among them, 4-(4-(4-(3-fluorophenyl)-1H-1,2,3-triazol-1-yl)phenoxy)-N-methylpicolinamide (8...

In the title carboxyl-ate-bridged binuclear copper complex, [Cu(2)(C(4)H(5)O(2))(4)(C(5)H(6)N(2))(2)], each Cu(II) ion has a distorted square-based pyramidal environment formed by one N and four O atoms. The asymmetric unit contains two halves of two centrosymmetric mol-ecules, with Cu⋯Cu separations of 2.6498 (8) and 2.6528 (8) Å.

The new binuclear chromium Pacman complex [Cr2(L)] of the Schiff base pyrrole macrocycle H4L has been synthesized and structurally characterized. Addition of isocyanide, C≡NR (R = xylyl, tBu), or triphenylphosphine oxide donors to [Cr2(L)] gives contrasting chemistry with the formation of the new coordination compounds [Cr2(μ-CNR)(L)], in which the isocyanides bridge the two Cr(II) centers, and...

In the centrosymmetric binuclear title complex, [Gd(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Gd(III) ions are linked by four 2-phen-oxy-propionate (L) groups in bi- and tridentate bridging modes. Each Gd(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate chelating carboxyl-ate group and four bridging carboxyl-ate groups in a distorted GdN(2)O(7) monocapped s...

In the centrosymmetric binuclear title complex, [Tb(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Tb(III) ions are linked by four 2-phen-oxy-propionate (L) groups through their bi- and tridentate bridging modes. Each Tb(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate carboxyl-ate group and four bridging carboxyl-ate groups in a distorted TbN(2)O(7) monocapped ...

The reaction of Cp*Sn[OTf] (Cp* = C 5 Me ; OTf O 3 SCF ) with one equivalent IPrNLi (IPrN bis(2,6-diisopropylphenyl)imidazolin-2-iminato) resulted in the binuclear [OTf]-bridged tin complex 1 . Similarly, [BF 4 ]-bridged bimetallic 2 was synthesized by Cp*Sn[BF ] (1 eq.). It also possible to prepare from via an anion exchange reaction. high-yield conversion into iodostannylene [IPrNSnI] accompl...

The title compound, [Cu(2)(C(10)H(7)Br(2)NO(4))(2)(C(10)H(8)N(2))]·H(2)O, is a binuclear copper(II) complex. Both Cu atoms are four-coordinate in a square-planar geometry. In addition, there is one water mol-ecule in the asymmetric unit. The crystal structure is stabilized by O-H⋯O and O-H⋯Br hydrogen bonds.

249 The compounds (CS(CH3h)Co(NO)X (X = CI, Br, I) have been prepared by reaction of [(CS(CH3)s)Coh(p.-NOh with the appropriate dihalogen X 2• Either by spontaneous decomposition or by addition of half an equivalent of [(CS(CH3)s)CoClh(p.-Clh, the chloro derivative forms the binuclear complex [(CS(CH3)s)CoClh(p.-NO)(p.-CI), the crystal structure of which indicates the presence of a nitrosyl bri...

The Schiff base ligand derived from the condensation of 3,5-dibromo-salicylaldehyde and 1,2-phenyl-enediamine, in the presence of dimethyl-formamide, forms the centrosymmetric title neutral binuclear distorted complex, [Cd(2)(C(20)H(10)Br(4)N(2)O(2))(2)(C(3)H(7)NO)(2)], with the two octa-hedral Cd atoms linked by two O atoms. All bond lengths and angles show normal values.
