In the title compound, {[Cu(C14H8O5)(C14H8N4)]·H2O} n , the CuII atom adopts a distorted cis-CuN2O2 square-planar coordination geometry. 4,4′-Oxydibenzoate (L) ligands link the CuII atoms, generating a helical chain. Neighbouring chains are linked through π–π interactions between pyrazino[2,3-f][1,10]phenanthroline ligands with a centroid–centroid distance of ca 3.44 Å, resulting in a two-dimensional supramolecular structure. The structure is completed by O—H...O hydrogen bonds.

In the CuIIcompoundcatena-poly[[copper(II)-μ-[2-({2-[2-(naphthalen-2-yloxy)-1-oxidoethylidene]hydrazin-1-ylidene}methyl)phenolato]] dimethylformamide monosolvate monohydrate], {[Cu(C19H14N2O3)]·C3H7NO·H2O}n, (I), the CuIIcation isO,N,O′-chelated by one ligand and furtherN,O-chelated by a second ligand, and exhibits a distorted square-pyramidal coordination environment. The ligand acts as an overall pentadentate bridge between two metal ions, thus forming a novel coordination polymer. In the trinuclear NiIIcompound diaquabis(1H-imidazole)bis[μ-2-oxido-N′-(1-oxido-2-phenoxyethylidene)benzohydrazidato]trinickel(II) dimethylformamide tetrasolvate, [Ni3(C15H11N2O4)2(C3H4N2)2(H2O)2]·4C3H7NO, (II), the three NiIIcations are directly linked by twotransdiazine (N—N) bridges and are strictly collinear by symmetry. The central NiIIcation, located on an inversion centre, is coordinated by two water O atoms and is furtherN,O-chelated by two 2-oxido-N′-(1-oxido-2-phenoxyethylidene)benzohydrazidate(3−) ligands in an elongated octahedral coordination geometry. The two terminal centrosymmetrically related NiIIcations are coordinated by an imidazole ligand andO,N,O′-chelated by a hydrazidate ligand in a distorted square-planar coordination geometry. Hydrogen bonds link individual molecules of (II) into a chain along [100].

The molecule of the title compound, [Rh(C42H62O3P)(C74H68O4P2]·2.7C7D8, consists of two phospharhodacyclic substructures sharing the Rh atom, which are formed by coordination/ortho-metallation of a triaryl phosphite, and by the coordination of a rigid bisphosphite, respectively. The metal displays a tetrahedrally distorted square-planar coordination geometry. Atert-butyl group shows rotational disorder over two positions with refined site occupancy of 0.561 (3):0.439 (3). Two partial-occupancy toluene solvent molecules are disordered over two orientations with site occupancies of 0.5:0.3 and 0.5:0.4, respectively. Intramolecular C—H...O hydrogen bonds are observed. In the crystal, complex molecules and toluene solvent molecules pack as alternating layers parallel to theacplane.
