摘要

不對稱配位基甲基，4-(嘧啶基-2-醯胺基)苯甲酸酯與二價鈷、鎳、
銅及一價銅進行反應， 可得到一系列的化合物:
[Co(L)2(CH3OH)2](ClO4)2 (L = methyl-4-(pyrimidin-2-ylcarbamoyl)-
benzoate), 1, [Co(L)2(CH3OH)2](BF4)2, 2, [Ni(L)2(CH3OH)2](BF4)2, 3,
[Cu(L)2(ClO4)2]⋅2CH3OH, 4, [Cu(L)2(BF4)2]⋅2CH3OH, 5, [Cu2(L)Cl4 ⋅
CH3CN]∞, 6, [Cu(L)2Br2]⋅CH3OH, 7, [Cu3.5(L)Br4⋅0.5C2H5OC2H5]∞, 8,
[Cu2(L)I2]∞, 9。化合物1 – 5 和7 為單核結構，化合物6 和8 為二維
結構，而化合物9 為一維鏈狀結構。藉由π---π stacking 或氫鍵等作用
力可使的化合物的維度上升。化合物1 – 5、7 和9 的配位基採用雙芽
的配位形式，化合物6 和8 則採用三芽的配位形式。另外配位基具有
cis 或trans 兩種構型。

The reactions of methyl-4-(pyrimidin-2-ylcarbamoyl)benzoate (L)
with Co(II), Ni(II), Cu(II) and Cu(I) metal salts afforded
[Co(L)2(CH3OH)2](ClO4)2, 1, [Co(L)2(CH3OH)2](BF4)2, 2,
[Ni(L)2(CH3OH)2](BF4)2, 3, [Cu(L)2(ClO4)2]⋅2CH3OH, 4,
[Cu(L)2(BF4)2]⋅2CH3OH, 5, [Cu2(L)Cl4⋅CH3CN]∞, 6, [Cu(L)2Br2]⋅CH3OH,
7, [Cu3.5(L)Br4⋅0.5C2H5OC2H5]∞, 8, and [Cu2(L)I2]∞, 9. All these
complexes were characterized by elemental analysis, IR spectra and
single crystal X-ray diffraction. Complexes 1 - 5 and 7 are mononuclear,
whereas complexes 6 and 8 show two-dimensional layers and 9 is a
one-dimensional chain. The L ligands of 1 - 5, 7 and 9 adopt the bidentate
mode, featuring chelation through one pyrimidyl nitrogen atom and the
amide oxygen atom and those of 6 and 8 adopts the tridentate mode
through the amide oxygen atom and both of the pyrimidyl nitrogen atoms.
The L ligands may adopt the cis or trans conformations. Moreover, π---π
stacking interactions and/or hydrogen bonds are found in these complexes
which extend the dimensionalities of the structures.
