Synthesis and spectroscopic characterization of copper, nickel and cobalt complexes with N-(N″,N″-disubstituted-aminothiocarbonyl)-N′-substituted benzamidines
A series of copper(II), nickel(II) and cobalt(III) complexes with N-(N″,N″-disubstituted-aminothiocarbonyl)-N′-substitutedbenzamides have been synthesized and characterized. 1H and 13C NMR spectra have shown a mer configuration for the CoL3 compounds. The NiL2 complexes have a square-planar structure. Electron spin resonance spectra have shown that the presence of a bulky substituent on the nitrogen
合成并表征了一系列具有N-(N '',N ''-二取代-氨基硫代羰基)-N'-取代的苯甲酰胺的铜(II),镍(II)和钴(III)配合物。1 H和13 C NMR光谱显示了COL 3化合物的mer构型。NiL 2复合物具有正方形平面结构。电子自旋共振谱表明,在氮供体原子上存在庞大的取代基会在CuL 2化合物的铜周围产生较大的四面体形变。循环伏安法已揭示了不可逆的氧化还原波,分别对应于Cu(III)Cu(II)和Cu(II)Cu(II)对。

The reaction of transition metal coordinated N,N-dialkylsubstituted N'-benzoyl thioureas with electrophilic agents differs from the reaction of the non-coordinated ligands. The nickel(II)chelates 1 form with organic acid chlorides RCOCI the N',N'-diacylated thioureas 2 and with thionyl chloride the n-(amino-thiocarbonyl)benzimide chlorides 3. The substitution of the chlorine in 3 yields new derivatives

Novel cationic rhenium(V) complexes with N-(thiocarbamoyl)benzamidinato ligands (R2tcb-) with the general formula [ReO(R2tcb)2](BPh4) have been prepared and characterized by elemental analysis, IR and NMR spectroscopy and mass spectrometry. The complexes are brown powders; crystalline products can only be obtained in the presence of triphenylphosphine oxide. [ReO(et2tcb)2](BPh4).OPPh3 has been studied with X-ray diffraction. The compound crystallizes triclinic in the space group P1BAR with a = 9.771(1), b = 16.886(1), c = 17.731(1) angstrom, alpha = 108.91(1), beta = 95.35(1), gamma = 104.36(1)-degrees, V = 2930 angstrom3 and Z = 2. The Re = O bond is 1.663(4) angstrom. The co-crystallization with tripenylphosphine oxide can be understood with the formation of hydrogen bonds between the NH protons of the chelate and the O atom of Ph3PO.
