Aqua­bis(2-iodo­acetato-κO)(1,10-phenanthroline-κ2 N,N′)copper(II)

In the title compound, [Cu(C2H2IO2)2(C12H8N2)(H2O)], the CuII ion is coordinated by two N atoms [Cu—N = 2.013 (4) and 2.024 (4) Å] from a 1,10-phenanthroline ligand and three O atoms [Cu—O = 1.940 (4)–2.261 (4) Å] from two carboxyl ligands and a water mol­ecule in a distorted square-pyramidal geometry. One iodo­acetate O atom [Cu—O = 2.775 (4) Å] completes the coordination to form a distorted octa­hedron. Inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers, which are further packed by π–π inter­actions between the 1,10-phenanthroline ligands into layers parallel to the ab plane. The crystal packing also exhibits short inter­molecular I⋯I contacts of 3.6772 (9) Å and weak C—H⋯O hydrogen bonds

Bis(2-bromo­acetato-κ2 O,O′)(1,10-phenanthroline-κ2 N,N′)copper(II)

The two halves of the title compound, [Cu(C2H2BrO2)2(C12H8N2)], are related by twofold symmetry along the b axis through the central CuII ion. The CuII ion is coordinated by two symmetry-related N atoms from the 1,10-phenanthroline ligand and four O atoms from two 2-bromo­acetate ligands, showing a distorted octahedral geometry. Weak inter­molecular C—H⋯O inter­actions link neighbouring mol­ecules

N′-(Diphenyl­methyl­ene)-2-hydroxy­benzo­hydrazide

In the title compound, C20H16N2O2, intra­molecular N—H⋯O and inter­molecular O—H⋯O hydrogen bonds are found. The inter­molecular hydrogen bonds link the mol­ecules into an infinite chain along the c axis. The dihedral angles between the aromatic rings are 16.9 (3), 80.8 (3) and 64.6 (3)
