Three novel copper(II) complex [Cu 2 (bpa)( μ ‐PhCO 2 )](ClO 4 ) 2 ( 1 ), [Cu 2 (bpa) ( μ ‐pyz)](ClO 4 ) 2 ( 2 ), and [Cu(Hbpa)](ClO 4 ) 2 ·2CH 3 CN ( 3 ) have been synthesized by the reaction of Hbpa with Cu(ClO 4 ) 2 ·6H 2 O in the presence and absence of exogenous ligands (where Hbpa = N, N'‐bis(picolinidene‐N‐oxide)‐2‐hydroxy‐1, 3‐diamino‐propane). Molecular structures of these compounds have been elucidated by single crystal X‐ray diffraction. 1 and 2 are both binuclear complexes in which two copper atoms are linked by the endogenous alkoxide oxygen and the exogenous benzoate and pyrazolate ligands, respectively. 3 consists of a one‐dimensional polymeric structure, in which Hbpa functions as a bridging mode.
