Synthesis and crystal structure of {N-(3-aminopropyl)iminodiacetato)(1,10-phenanthroline)copper(II) pentahydrate [cu(apida)(phen)] .5H2O

The crystal structure of [Cu(Apida)(Phen)].5H 2 O (I) is determined by X-ray diffraction. The crystals are triclinic: a = 8.159(1) A, b = 9.595(1) A, c = 16.039(4) A, a = 91.42(3)°, β = 98.25(3)°, γ = 110.94(1)°, Z =2, space group P1 (direct methods; water H atoms are located, the others are introduced geometrically; anisotropic, isotropic for H atoms, least-squares method; R1 = 0.051, wR2 = 0.149, GOOF = 1.142). The Cu atom in the molecular structure is coordinated by two N atoms of the Phen molecule and by four (2N + 20) atoms of the Apida ligand. The coordination number of Cu is 4 + 2. The axial Cu-N(Phen) and Cu-O(Apida), bond lengths are 2.35 and 2.38 A, respectively; the equatorial Cu-N(Apida), Cu-O(Apida), and Cu-N(Phen) bond lengths are 2.07 (av.), 2.01, and 2.06 A, respectively.
