  摘要：

  The phase relations in the CuSe-CrSe-TiSe system are studied. The system is shown to contain CuCr1-xTixSe2 solid solutions isostructural with CuCrSe2. The solid-solution range and the oxidation states of Cr and Ti are determined, and the ionic conductivity of the solid solutions is measured.

• Synthesis of phosphinochalcogenoic amidato complexes of divalent transition metals and their thermolysis to metal selenide and telluride phases

  Protolysis of the transition-metal diamides [MN(SiMe 3 ) 2 } 2 (thf) n ] (M = Cr, Mn, Fe or Co) with 2 equivalents of phosphinochalcogenoic amides Bu t 2 P(E)NHR (E = Se or Te, R = Pr i or cyclo-C 6 H 11 ) gave a series of thermally stable metal–selenium and –tellurium complexes [MBu t 2 P(E)NR} 2 ]. The complex [NiBu t 2 P(Se)NR} 2 ] was obtained from Li[Bu t 2 (Se)NR] and [NiCl 2 (PMe 3 ) 2 ]. The compounds sublime readily under reduced pressure and are suitable for the gas-phase deposition of metal chalcogenide films. The selenium precursors lead to MSe (M = Cr, Mn, Fe or Ni), while tellurium complexes afford MTe 2 (M = Fe, Mn or Co). By contrast, [CoBu t 2 P(Se)NR} 2 ] gives Co 3 Se 4 , while [NiBu t 2 P(Se)NR} 2 ] generates NiSe or Ni 6 Se 5 , depending on the deposition conditions.

  过渡金属二酰胺的原解离反应 [MN(SiMe₃)₂}₂(thf)ₙ]（M = Cr, Mn, Fe 或 Co）与两个当量的磷氟硫氨基化合物 Bu₂P(E)NHR（E = Se 或 Te，R = Pr₁ 或环己烷）反应，生成了一系列热稳定的金属-硒和-碲配合物 [MBu₂P(E)NR}₂]。配合物 [NiBu₂P(Se)NR}₂] 是由 Li[Bu₂(Se)NR] 和 [NiCl₂(PMe₃)₂] 反应获得的。这些化合物在减压下易于升华，并适合用于金属硫族化物薄膜的气相沉积。硒前体导致 MSe（M = Cr, Mn, Fe 或 Ni），而碲配合物则提供 MTe₂（M = Fe, Mn 或 Co）。相反，[CoBu₂P(Se)NR}₂] 生成 Co₃Se₄，而 [NiBu₂P(Se)NR}₂] 则根据沉积条件生成 NiSe 或 Ni₆Se₅。

  Transmetallation of the dichalcogenide complexes [CpMn(CO)(2)](2)(mu-X-2) (X = S or Se) with M(CO)(5)(thf) (M = Cr or W) afforded new heterometallic complexes CpMn(CO)(2)(ASe(2))Cr(CO)(5), CpMn(CO)(2)(mu-Se-2)[Cr(CO)(5)](2), CpMn(CO)(2)(mu-X-2)[W(CO)(5)](2) (X = S or Se), and CpMn(CO)(2)(mu-Se-2)[Cr(CO)(5)][W(CO)(5)]. According to the X-ray diffraction data, their molecular structures contain the cyclic MnX2 fragments coordinated by one or two M(CO)(5) groups via the X atoms. Study of thermal decomposition of the manganese complexes with different Mn : M : X ratios (M = Cr, W; X = S, Se, Te) by differential scanning calorimetry (DSC) and thermogravimetry demonstrated that this process took place at rather low temperatures (100-400degreesC) and was accompanied by complete elimination of the CO groups followed by elimination of the Cp groups. At any metal to chalcogen ratio, the resulting inorganic chalcogenides contained no impurities of metal oxides and carbides.
