Structures of chloro(glycinato)(1,10-phenanthroline)copper(II) monohydrate (I) and aqua(1,10-phenanthroline)(L-phenylalaninato)copper(II) nitrate monohydrate (II).

(I) [CuCl(C2H4NO2)(C12H8N2)].H2O, Mr = 371.28, orthorhombic, P2(1)2(1)2(1), a = 6.795 (3), b = 12.496 (4), c = 17.273 (5) A, V = 1467 (1) A3, Dx = 1.680 Mg m-3, Z = 4, F(000) = 756, lambda(Mo K alpha) = 0.71069 A, mu(Mo K alpha) = 1.742mm-1. Room temperature. Final R = 0.046 for 1302 unique observed reflections. (II) [Cu(C9H10NO2)(C12H8N2)(H2O)]NO3.-H2O, Mr = 505.98, monoclinic, P2(1), a = 5.782 (2), b = 20.700 (6), c = 9.355 (3) A, beta = 97.58 (2)degrees, V = 1110 (1) A3, Dx = 1.514 Mg m-3, Z = 2, F(000) = 522, lambda(Mo K alpha) = 0.71069 A, mu(Mo K alpha) = 1.076 mm-1. Room temperature. Final R = 0.069 for 1929 unique observed reflections. The Cu ion displays distorted square-pyramidal coordination in both (I) and (II), with the chlorine atom (I) or the water molecule (II) in the apical position. The Cu-N bond lengths alter according to the electronegative character of the trans atom. The conformations of the five-membered chelate rings appear to depend on H bonding and van der Waals interactions.
