The cadmium(II) complexes of 2,4-dithiobiuret (Hdtb=L) : Cd2L3Cl4, CdL2X2 (X=Br, I, ClO4), CdL3SO4·H2O and CdL4(NO3)2 have been prepared and investigated by i.r. spectra. In all these complexes Hdtb is S-coordinated, principally behaving as a monodentate ligand, in some cases with a weaker interaction of the second thiocarbonylic sulphur atom. In the halide complexes the cadmium ion is six coordinated with halide bridging ions.

制备了2,4-二硫脲(Hdtb=L): Cd2L3Cl4、CdL2X2 (X=Br, I, ClO4)、CdL3SO4·H2O和CdL4(NO3)2的镉(II)配合物，并用红外光谱对其进行了研究。在所有这些配合物中，Hdtb是s配位的，主要表现为单齿配体，在某些情况下与第二个硫代羰基硫原子的相互作用较弱。在卤化物配合物中，镉离子与卤化物桥接离子六配位。

A dominant contribution from the chemical shift anisotropy relaxation mechanism to205Tl spin-lattice relaxation in some dialkylthallium(III) derivatives is demonstrated by measurements at two different fields and is also reflected in nmr linewidths of coupled protons, hence suggesting a new and facile method for monitoring changes in205Tl T1 values.

The structures of five cation distortion isomers of the five-coordinate [Cu(bpy)2Cl]+ cation range from trigonal bipyramidal to square pyramidal distorted trigonal bipyramidal, restricted by the bite of the 2,2′-bipyridyl ligands. The structures may be related by a structural profile involving a linear combination of the ν7 and ν8 modes of vibration of a trigonal bipyramidal CuN2N2'Cl chromophore in C2V symmetry.

五坐标[Cu(bpy)2Cl]+阳离子的五种阳离子畸变异构体的结构受2,2 ' -联吡啶配体的咬合作用的限制，从三角双锥体到方锥体畸变三角双锥体。这些结构可能与C2V对称的三角形双锥体CuN2N2'Cl发色团ν7和ν8振动模式的线性组合有关。
