Description
Summary:Reaction products of Cu(II) 2-chlorobenzoate and 4-aminopyridine (1), and of Cu(II) 2,6-dichlorobenzoate and 4-aminopyridine (2) formulated as CuL′ 2 (4-apy) 2 and CuL″ 2 (4-apy) 2 ((L′ =C 7 H 4 ClO − 2 ,L″ =C 7 H 3 Cl 2 O − 2 , 4-apy = 4-aminopyridine), were prepared and characterized by structural and spectroscopic measurements, thermochemical properties and magnetic susceptibilities. Compound (1) crystallizes in the orthorhombic space group Pbca, a = 8.875(2), b = 13.236(4), c = 21.603(3) Å, V = 2537.7(10) Å 3 , Z = 4, and the Compound (2) crystallizes in the monoclinic space group P2 1 /c, a = 11.516(2), b = 8.749(2), c = 13.469(3) Å, β = 103.36(3)°, V = 1320.3(5) Å 3 , Z = 2. Complexes (1) and (2) decomposes to gaseous products at 473 and 513 K, respectively.
