The reaction of dichloridotetrakis(dimethyl sulfoxide)ruthenium(II) withN,N-bis[(pyridin-2-yl)methyl]methylamine affords the title complex, [RuCl2(C13H15N3)(C2H6OS)]. The asymmetric unit contains a well-ordered complex molecule. TheN,N-bis[(pyridin-2-yl)methyl]methylamine (bpma) ligand binds the cation through its two pyridyl N atoms and one aliphatic N atom in a facial manner. The coordination sphere of the low-spind6RuIIis distorted octahedral. The dimethyl sulfoxide (dmso) ligand coordinates to the cation through its S atom and iscisto the aliphatic N atom. The two chloride ligands occupy the remaining sites. The bpma ligand is folded with the dihedral angle between the mean planes passing through its two pyridine rings being 64.55 (8)°. The two N—Ru—N bite angles of the ligand at 81.70 (7) and 82.34 (8)° illustrate the distorted octahedral coordination geometry of the RuIIcation. Two neighboring molecules are weakly associated through mutual intermolecular hydrogen bonding involving the O atom and one of the methyl groups of the dmso ligand. One of the chloride ligands is also weakly hydrogen bonded to a pyridyl H atom of another molecule.

Reaction of indium(III) chloride with (E)-1-[1-(2-pyridyl)ethylidene]thiosemicarbazide afforded the title complex, [In(C8H9N4S)Cl2(C2H5OH)]. The ligand is in the enol form coordinating to the InIII atom through one S atom and two N atoms. The InIII atom is further coordinated by two Cl atoms and an ethanol molecule to complete a distorted octahedral coordination geometry.

The Ni atom in the title complex, [Ni(C2H3O2)2(C15H13N5)] or [Ni(CH3COO)2(tpdaH2)] (tpdaH2 is tripyridyldiamine), has a distorted octahedral coordination geometry formed by the tridentate tpdaH2 ligand and two acetate groups. The tpdaH2 ligand is mer-coordinated, with the N atom of the central pyridine ring in the equatorial position and the N atoms of the peripheral pyridine rings in the axial positions. The remaining three equatorial positions are occupied by the O atoms of two acetate anions. The H atoms of both NH groups of the tpdaH2 ligand are involved in strong hydrogen bonds with O atoms of adjacent complex molecules to form a three-dimensional network.

In the polymeric title complex, [MnBr2(C10H8N2)] n , the MnII ion, situated on a twofold axis of symmetry, is six-coordinated in a distorted octahedral coordination geometry defined by two N atoms from the chelating 2,2′-bipyridine ligand and four bridging Br− anions. The crystal reveals a one-dimensional Br-bridged chain along the c-axis direction with a zigzag topology. In the crystals, contacts between chains include π–π interactions between pyridyl rings [inter-centroid separation = 4.082 (1) Å]

In the mononuclear title complex, [Co(C10H6NO4)2(C7H10N2)2(H2O)2], the CoII ion is located on an inversion centre and has a distorted octahedral coordination geometry of type CoN2O4 by two N atoms from the two 4-(dimethylamino)pyridine (DMAP) ligands, two carboxylate O atoms from the two deprotonated N-phthaloylglycine (Nphgly) ligands [systematic name: 2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)acetate] and two coordination water molecules. In the crystal, O—H...O, C—H...O hydrogen bonds and π–π stacking interactions link the molecules into the supramolecular structure.

In the title complex, [Ru(C12H8N2)2(C5H6N2)2](PF6)2, the RuIIatom is bonded to two α-diimine ligands,viz.1,10-phenanthroline (phen), in acisconfiguration, in addition with with two 4-aminopyridine (4Apy) ligands, resulting in a distorted octahedral coordination geometry. N—H...F hydrogen-bonding interactions play an important role in the crystal assembly: 21-screw-axis-related complex molecules and PF6−counter-ions alternate in helical chains formed along theaaxis by means of these contacts. N—H...π contacts (H...centroid = 3.45 Å) are responsible for cross-linking between the helical chains along [001].

In the title complex, [Cu(C8H4O4)(C10H9N3)] n , the benzene-1,4-dicarboxylate dianions bridge the CuII atoms to form polymeric complex chains. The CuII atom has a distorted octahedral coordination geometry. The centroid-to-centroid separation of 3.932 (2) Å indicates π–π stacking between nearly parallel pyridine rings.

The asymmetric unit of the title complex [Cu(C14H12N2)2]2[Fe(CN)5(NO)], consists of a [Cu(dmp)2]+cation (dmp is 2,9-dimethyl-1,10-phenanthroline) and half an [Fe(CN)5(NO)]2−anion. The anion is disordered across an inversion center with the FeIIion slightly offset (ca0.205Å) from the inversion center in the direction of the disorderedtrans-coordinating CN/NO ligands. The anion has a distorted octahedral coordination geometry. The CuIion is coordinated by two phenanthroline ligands in a distorted tetrahedral geometry. The dihedral angle between the phenanthroline ligands is 77.16 (4) Å. In the crystal, the cations are connected to the anions by weak C—H...N hydrogen bonds. In addition, weak π–π stacking interactions are observed, with centroid–centroid distances in the range 3.512 (3)–3.859 (3) Å.

The structure of the dinuclear title complex, [Cu2(C10H8N7)2(NO3)2(H2O)2]·2H2O, consists of centrosymmetric dimeric units with a copper–copper separation of 4.0408 (3) Å. The CuIIions in the dimer display a distorted octahedral coordination geometry and are bridged by two triazole rings, forming an approximately planar Cu2N4core (r.m.s. deviation = 0.049 Å). In the crystal, O—H...O, O—H...N and C—H...O hydrogen bonds and π–π interactions link the molecules into a three-dimensional network.

The title compound, {[Cd3(C6H13N2)2Cl8]·2H2O}n, consists of pendant protonated cationic diamine ligands bonded to an anionic one-dimensional coordination polymer chloridocadmate scaffold. Each coordination chain features two kinds of CdIIcentre, each with distorted octahedral coordination geometry. One CdIIcation lies on a centre of inversion and is coordinated by six bridging chloride ligands, while the other is coordinated by four bridging chloride ligands, one terminal chloride ligand and a 1-aza-4-azoniabicyclo[2.2.2]octane aza N atom. This gives a reversible corner-sharing half-cubic linear polymer that lies along the crystallographicadirection. The chains interact through hydrogen bonding with solvent water, with each water molecule accepting one N—H...O interaction from a cation and donating to two O—H...Cl interactions with anionic chains, thus linking three separate chains and completing the packing structure.

The title complex, systematic name hexakis(μ2-4-tert-butoxy-4-oxobut-2-en-2-olato)-1:2κ9O2,O4:O2;2:3κ9O2,O4:O2-trizinc, [Zn3(C8H13O3)6], synthesized fromtert-butyl acetoacetate and diethylzinc, consists of trinuclear centrosymmetric molecules of an approximateC3isymmetry. The three metal cations are arranged in a linear fashion, with the central ZnIIatom located on a centre of symmetry. All three metal cations exhibit a distorted octahedral coordination geometry. The terminal ZnIIcations are chelated by threetert-butyl acetoacetate ligands and these units are connected to the central ZnIIatom by the bridging enolate O atoms.
