由[Cu(salpd)]和乙酸铜(II)或甲酸铜(II)以定量收率合成了标题配合物，其中H2salpd代表N,N'-二水杨基-1,3-丙二胺。 [Cu(salpd-μ-O,O')(μ-L)Cu(μ-CH3O)2Cu(μ-L)(salpd-μ-O,O')Cu]结晶于单斜空间群P21/n，分子式=Cu4C40H44N4O10，F.W.=995.0，a=11.826(2) A，b=17.192(4) A、c=9.836(2) A、β=94.08(2)°、V=1994.8(7) A3 和 Z=2 (R=3.83%)，其中 L=CH3COO。该配合物形成由两个[Cu(salpd-μ-O,O')(μ-CH3COO)Cu]单元通过一对甲氧桥连接而成的中心对称分子；每个末端铜(II)离子与salpd的N和O原子形成四个短键，并与乙酰基的一个氧原子形成一个稍长的(2.235(4) A)轴向键，而每个内部铜(II)离子也由两个甲氧基氧、一个乙酰氧和一个桥接salpd氧以金字塔方式配位，远处的轴向位置被占据(Cu-O=2.323(3) A)剩余的桥接salpd 氧。磁...
The title complexes have been synthesized in quantitative yield from [Cu(salpd)] and copper(II) acetate or copper(II) formate , where H2salpd represents N,N′-disalicylidene-1,3-propanediamine. [Cu(salpd-μ-O,O′)(μ-L)Cu(μ-CH3O)2Cu(μ-L)(salpd-μ-O,O′)Cu] crystallizes in the monoclinic space group P21/n with formula=Cu4C40H44N4O10, F.W.=995.0, a=11.826(2) A, b=17.192(4) A, c=9.836(2) A, β=94.08(2)°, V=1994.8(7) A3 and Z=2 (R=3.83%), where L=CH3COO. The complex forms a centrosymmetric molecule made up of two units of [Cu(salpd-μ-O,O′)(μ-CH3COO)Cu] bound by a pair of methoxo bridges; each terminal copper(II) ion forms four short bonds with N and O atoms of salpd and a slightly longer (2.235(4) A) axial bond with one of the oxygens of the acetato group, whereas each inner copper(II) ion is also pyramidally coordinated by two methoxo oxygens, one of the acetato oxygens, and one of the bridging salpd oxygens, the distant axial position being occupied (Cu–O=2.323(3) A) by the remaining bridging salpd oxygen. The mag...
