The title compound, [Cr(CN)2(C12H8N2)2][Cr(N3)2(C18H12N4O2)]·H2O, contains [CrIII(CN)2(phen)2]+ cations (phen is 1,10-phenanthroline) and [CrIII(N3)2(bpb)]− anions [bpb is 1,2-bis(pyridine-2-carboxamido)benzene or N,N′-(o-phenylene)bis(pyridine-2-carboxamide)]. In the cations, the CrIII atom is coordinated by two phen ligands and two cyanide ligands in a distorted octahedral geometry. In the anions, the CrIII atom is coordinated by the tetradentate bpb ligand and two azide ions, forming a distorted octahedral geometry. There is one solvent water molecule per cation–anion pair, which forms hydrogen bonds to one carbonyl group of the bpb ligand and to the terminal N atom of one cyanide ligand.

The ZnIIatom in the title polymeric compound, {[Zn(C8H6NO4)2(H2O)2]·2H2O}n, lies on a center of inversion and is coordinated by two amine N atoms and two carboxylate O atoms from two 3-amino-5-carboxybenzoate anions along with two water molecules in a distorted octahedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds of the N—H...O and O—H...O types exist in the structure. One H atom of the coordinated water molecule and one H atom of the solvent water molecule are each disordered over two positions in a 1:1 ratio.

In the title compound, [Ni(C12H6O4)(C21H18N4)(H2O)]n, the NiIIcation is coordinated by three carboxylate O atoms of two naphthalene-1,4-dicarboxylate anions, one water molecule and two N atoms of two 1,1′-(9,9-dimethyl-9H-fluoren-2,7-diyl)di-1H-imidazole (DFDI) ligands, giving rise to a slightly distorted octahedral geometry. The NiIIions are linked by the DFDI ligands into chains, which are further connected by the carboxylate anions into double chains that elongate in the theb-axis direction. These double chains are linked by centrosymmetric pairs of O—H...O hydrogen bonds into layers parallel to (10-1). The asymmetric unit consists of one crystallographically independent NiIIcation, one carboxylate and one DFDI ligand, as well as of one water molecule, all of them located in general positions.

The title compound, [Cu2(NO3)2(OH)2(C12H8N4O)2(H2O)2]n, consists of a neutral polymeric CuIIcomplex in which each CuIIatom has a distorted octahedral geometry defined by a pyridyl N atom from a 3-(pyridin-3-yl)-5-(pyridin-4-yl)-1,2,4-oxadiazole ligand and five O atoms from a water molecule, two nitrates and two hydroxides. Two CuIIions are bridged by two hydroxide anions resulting in a Cu2O2loop, located across an inversion center and connected by the nitrate anions into a broad two-dimensional polymeric structure parallel to (100). In the crystal, there are O—H...O hydrogen bonds between the coodinated water molecule and the nitrate and hydroxide, and between the hydroxide and the nitrate. Intermolecular π–π interactions are present between pyridine rings in adjacent two-dimensional structures, with a centroid–centroid distance of 3.582 (2) Å.

In the title compound, [Cu(C11H8NO3)(CH3COO)(C10H8N2)]n, the CuIIion is six-coordinated by two N atoms from two 4,4′-bipyridine ligands, four O atoms from one acetate ligand, one 2-(4-oxo-1,4-dihydroquinolin-1-yl)acetate ligand and one water molecule in a distorted octahedral geometry. The 4,4′-bipyridine ligands interconnect [Cu(C11H8NO3)(CH3COO)] units, giving rise to a chain along [010]. These chains are further linked to each other by O—H...O hydrogen bonds, leading to a two-dimensional supramolecular network parallel to (100).

The asymmetric unit of the title compound, [Mn(C6H6N4)2(H2O)2](C8H4O4), contains one-half each of the centrosymmetric cation and anion. The MnII atom is coordinated by four N atoms [Mn—N = 2.2168 (14) and 2.2407 (14) Å] from two 2,2′-biimidazole ligands and two water molecules [Mn—O = 2.2521 (14) Å] in a distorted octahedral geometry. Intermolecular N—H...O and O—H...O hydrogen bonds consolidate the crystal packing, which also exhibits π–π interactions between five-membered rings, with a centroid–centroid distance of 3.409 (2) Å.

In the title compound, [Cd(C2H8N2)3](GeF6), the CdIIatom, lying on a 32 symmetry site, is coordinated by six N atoms from three ethylenediamine (en) ligands in a distorted octahedral geometry. The Ge atom also lies on a 32 symmetry site and is coordinated by six F atoms. The en ligand has a twofold rotation axis passing through the mid-point of the C—C bond. The F atom is disordered over two sites with equal occupancy factors.

The asymmetric unit of the title compound, {[Mn3{W(CN)8}2(C16H16N2)3(C3H7NO)3(CH3OH)3]·2H2O}n, consists of three [Mn(N,N-dimethylformamide)(methanol)(3,4,7,8-tetramethyl-1,10-phenanthroline)]2+cations, two [W(CN)8]3−anions and two water molecules. Each water molecule is disordered over three sets of sites, with a refined occupancy ratio of 0.310 (9):0.275 (9):0.415 (9) for one molecule and 0.335 (9):0.288 (9):0.377 (9) for the other molecule. The MnIIatoms exhibit a distorted octahedral geometry, while the WVatoms adopt a distorted square-antiprismatic geometry. The MnIIand WVatoms are linked alternatively through cyanide groups, forming a tetranuclear 12-atom rhombic metallacycle. Adjacent metallacycles are further connected by μ2-bridging cyanide anions, generating a 3,2-chain structure running parallel to [101]. Interchain π–π interactions are observed [centroid–centroid distances = 3.763 (3) and 3.620 (2) Å].
