四核铜以α-过硫代萘酸为配体的新原子簇化合物Cu_4(α-C_(10)H_7·CSS_2)_4·1/2 CS_2由α-萘荒酸钠与氯化铜在碱性水溶液中或者用α-萘荒酸与氯化铜在有机溶剂中反应生成.经CS_2—C_2H_5OH重结晶,得红色晶体.用X射线单晶衍射法测定了晶体结构.晶体属单斜晶系,空间群为C_(2h)~5-P 2_1/a,晶胞参数:α=16.453(3)A,b=12.651(4)A,C=23.182(7)A,β=100.5(2)°V=4744.6A~3’Z=4.经最小二乘修正后,最终的偏差因子R=0.06、Cu_4呈稍变形的四面体构型.四个α-过硫代萘酸通过S原子与Cu配位.每个配体中有一个S同时与两个Cu配位(形成硫桥),另一个S只与一个Cu配位.Cu原子与相配位的三个S原子基本共面.每个Cu原子与—CSS_2基因形成五元环,此五元环基本上处于同一平面上.分子中近似地有四重反轴(S_4)对称性。 在该原子簇化合物生成过程中,发生了氧化还原作用.本文对反应机理进行了探讨。
Tetra-nuclear copper New α-cluster compounds with α-peroxynaphthalene as the ligand Cu_4 (α-C_ (10) H_7 · CSS_2) _4 · 1/2 CS_2 In aqueous solution or with α-naphthalene acid and copper chloride in organic solvent reaction generated by the CS_2-C_2H_5OH recrystallization, red crystals obtained by X-ray single crystal diffraction method for the determination of the crystal structure of the crystal is monoclinic , The space group is C_ (2h) ~ 5-P 2_1 / a, the unit cell parameters are α = 16.453 (3) A, b = 12.651 (4) A, C = 23.182 (7) A, ° V = 4744.6A ~ 3’Z = 4. After the least squares correction, the final deviation factor R = 0.06, Cu_4 slightly deformed tetrahedron configuration.The four α-peroxynaphthalene by S atom and Cu ligands.Each ligand has one S at the same time with two Cu (sulfur bridges formed), the other S only with a Cu coordination.Cu atoms and the coordination of the three S atoms are basically co-planar.Each The Cu atoms form a five-membered ring with the -CSS_2 gene, and the five-membered rings are substantially in the same plane, and the molecules have an approximately quadrilateral (S 4) symmetry symmetry. During the formation of this cluster compound, redox reaction took place. The reaction mechanism was discussed in this paper.
