Summary: | 碩士 === 中原大學 === 化學研究所 === 93 === A series of silver(I) complexes of the types [Ag(ABrPm)]4(NO3)4 • H2O, 1, {[Ag(ABrPm)](ClO4)}n, 2, {[Ag(ABrPm)](PF6) • C2H5OH}n, 3, [Ag(ABrPm)2]2(PF6)2 • C2H5OH, 4 and [Ag3(ABrPm)4](BF4)3 • CH3OH, 5, have been prepared by the reactions of ABrPm ligands (ABrPm = 2-amino-5-bromopyrimidine ) with Ag(I) slats (AgNO3, AgClO4, AgPF6 and AgBF4 ).
All the complexes have been structurally characterized by X-ray crystallography confirming that complexes 2, 3 and 5 are coordination polymers. Complexes 2 and 3 form helical chains and complex 5 forms a chain structure with linear matallocycles. Complex 1 is tetranuclear while complex 4 is mononuclear. In complex 1 and 2, the molecular chains are interacted through Ag---O interactions and N-H---O hydrogen bonds. In complex 3 ~ 5, the chains or molecules are interacted through Ag---F interactions and N-H---F hydrogen bonds. Complex 3 shows N-H---O, C-H---F and C-H---N hydrogen bonds, while complex 4 shows N-H---N and C-H---F hydrogen bonds.
