N2 - Two new copper(II) complexes, trans-[Cu(L1)2(MeOH)2](ClO4)2 (1) and trans-[Cu(L2)2(ClO4)2]·2MeCN (2) (L1 =3-(2-pyridyl)-4-phenyl-5-(2-thienyl)-1,2,4-triazole, L2=3-(2-pyridyl)-4-(p-chlorophenyl)-5-(2-thienyl)-1,2,4triazole), were synthesized and structurally characterized by FT-IR, elemental analyses, single-crystal X-ray crystallography and powder X-ray diffraction. Both 1 and 2 crystallize in monoclinic system with a space group P21/c. X-ray crystallography analysis reveals that the copper ion in 1 and 2 sits in a distorted octahedral environment [CuN4O2] with two MeOH in the trans-position in 1 but two ClO4- in the trans-position in 2. Each L ligand in the equatorial plane adopts a chelating bidentate mode through the pyridyl N atom and one triazole N atom, while the thienyl group does not coordinate. 2 contains two MeCN guest molecules which produce π-π stacking interactions with the triazole ring. In 1 and 2 there are some intermolecular O—H…O, C—H…O and C—H…N hydrogen bonds and C—H…π interactions, linking the mononuclear complexes to form a 3D framework. CCDC: 2423470, 1; 2423471, 2.
