The title compound, [Fe2Yb2(CN)12(C4H9NO)5(H2O)6]·2H2O, is a tetranuclear complex, where the four metal centres are connected through three cyano bridges, the iron centres making one and two bridges, respectively. Each Fe atom is surrounded by six cyano ligands, forming almost ideal octahedra. The two Yb atoms have different ligand environments; both are coordinated by seven ligands, consisting of water molecules, dimethylacetamide (DMA) solvent and cyano groups, but not in the same ratio. Four of the five DMA molecules show various degrees of common structural disorder. The asymmetric unit also includes two solvent water molecules, which take part in hydrogen bonding, forming an extended network of tetramers.

The asymmetric unit of the title compound, dipotassium bis[hexaaquanickel(II)] tris(μ2-methylenediphosphonato)tripalladium(II) hexahydrate, K2[Ni(H2O)6]2[Pd3{CH2(PO3)2}3]·6H2O, consists of half a {[Pd{CH2(PO3)2}]3}6−anion [one Pd atom (4e) and a methylene C atom (4e) occupy positions on a twofold axis] in a rare `handbell-like' arrangement, with K+and [Ni(H2O)6]2+cations to form the neutral complex, completed by three solvent water molecules. The {[Pd{CH2(PO3)2}]3}6−units exhibit close Pd...Pd separations of 3.0469 (4) Å and are packedviaintermolecular C—H...Pd hydrogen bonds. The [KO9] and [NiO6] units are assembled into sheets coplanar with (011) and stacked along the [100] direction. Within these sheets there are [K4Ni4O8] and [K2Ni2O4] loops. Successive alternation of the sheets and [Pd{CH2(PO3)2}]3units parallel to [001] produces the three-dimensional packing, which is also supported by a dense network of hydrogen bonds involving the solvent water molecules.

Type Complex

The title compound, [Co2(C9H4N2O4)2(H2O)8]·5H2O, contains two CoII ions that are bridged by two 1H-benzimidazole-5,6-dicarboxylate ligands to form an M 2 L 2 type complex (M = metal and L = ligand). There are two crystallographically distinct M 2 L 2 units, each on an inversion centre, along with coordinated and uncoordinated water molecules, in the asymmetric unit. The CoII ions are octahedral. Extensive hydrogen bonding exists between the complex and water molecules, and this helps to stabilize the crystal structure. One water molecule is disordered over two sites with occupancies 0.84:0.16.

Independent Molecules

In the asymmetric unit, equalling the unit cell (triclinic,P1,Z= 1), two molecules of the title compound, 8-(4-methylphenyl)-D-2′-deoxyadenosine, C17H19N5O3, are present, with distinct conformations of the two sugar moieties, together with one solvent water molecule. All three ribose O atoms are involved in hydrogen bonding and the crystal packing is largely determined by hydrogen-bonding or hydrogen–heteroatom interactions (O—H...O, O—H...N, N—H...O, C—H...O and C—H...N) with one independent molecule directly linked to four neighbouring molecules and the other molecule directly linked to six neighbouring molecules. The two independent molecules of the asymmetric unit display three weak intramolecular C—H-to-heteroatom contacts, two of which are very similar despite the different conformations of the deoxyribosyl moieties. The aromatic ring systems of both molecules are in proximity to each other and somehow aligned, though not coplanar. The absolute structures of the two molecules were assumed with reference to the reactant 8-bromo-D-2′-deoxyadenosine as they could not be determined crystallographically.

In the mononuclear title compound, [Cd(C8H5O3)2(C10H8N2)(H2O)]·H2O, the Cd atom is O,O′-chelated by two 4-formylbenzoate monoanions and N,N′-chelated by 2,2′-bipyridine. It is also coordinated by a water molecule in a monocapped trigonal-prismatic geometry. The coordinated and solvent water molecules and O atoms of the monoanions engage in hydrogen bonding, resulting in a chain running along the b axis of the monoclinic unit cell.

The asymmetric unit of the crystal structure of the title compound, C25H18N2·0.5H2O, contains two independent dipyridylspiro(cyclopropanefluorene) (CPF) molecules and one solvent water molecule. The two CPF molecules show significantly different dihedral angles between the pyridine rings and fluorene plane. The water molecule links with the CPF molecules via O—H...N hydrogen bonding to form a one-dimensional supramolecular chain.

In the structure of the title compound, (NH4)8[Cu4(C2O4)8(H2O)2]·4H2O, isolated tetramers of [Cu(ox)2]2+ (ox is oxalate) are present. Each CuII ion coordinates to four O atoms in two oxalate ligands and to two more distant O atoms in a neighbouring oxalate ligand or a water molecule. An extensive hydrogen-bonding network connects the tetramers to two unique solvent water molecules and four ammonium ions.
