A new tetranuclear mixed-valence cobalt complex, namely di-μ2-azido-diazidodiethanolbis{μ2-2-[(hydroxyimino)methyl]-6-methoxyphenolato}bis{μ3-6-methoxy-2-[(oxidoimino)methyl]phenolato}dicobalt(II)dicobalt(III) ethanol disolvate, [CoII2CoIII2(C8H7NO3)2(C8H8NO3)2(N3)4(C2H5OH)2]·2C2H5OH, has been synthesized by the reaction of Co(OAc)2·4H2O (OAc is acetate) with 3-methoxysalicylaldoxime (H2mosao) in an ethanol solution. In the complex, the four Co cations all display distorted octahedral coordination environments and they are bridged by two κ2,κ1,κ1;μ3-mosao2−ligands, two κ2,κ2;μ2-Hmosao−ligands and two μ2-N3−anions to form a tetranuclear [Co4N4O4] cluster. Adjacent clusters are connected through weak C—H...N and C—H...O interactions, resulting in a two-dimensional supramolecular network parallel to theacplane. The magnetic properties of the complex have also been studied.

A cadmium–thiocyanate complex, poly[(1-cyanomethyl-4-aza-1-azoniabicyclo[2.2.2]octane-κ4N)octakis-μ2-thiocyanato-κ8N:S;κ8S:N-tricadmium(II)], [Cd3(C8H14N3)2(NCS)8]n, was synthesized by the reaction of 1-cyanomethyl-4-aza-1-azoniabicyclo[2.2.2]octane chloride, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, there are two independent types of CdIIcation (one on a centre of inversion and one in a general position) and both are in distorted octahedral coordination environments, coordinated by N and S atoms from different ligands. Neighbouring CdIIcations are linked together by thiocyanate bridges to form a two-dimensional network. Hydrogen-bonding interactions are involved in the formation of a three-dimensional supramolecular network.

Distorted Octahedral Coordination Environment

In the title coordination polymer, [Cd2(SO4)2(C13H8N4)(H2O)2]n, there are two crystallographically independent CdIIcentres with different coordination geometries. The first CdIIcentre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, giving a distorted octahedral coordination environment. The second CdIIcentre is heptacoordinated by four O atoms of three sulfate ligands, one water O atom and two N atoms of one chelating IP ligand, resulting in a distorted monocappedanti-trigonal prismatic geometry. The symmetry-independent CdIIions are bridged in an alternating fashion by sulfate ligands, forming one-dimensional ladder-like chains which are connected through the IP ligands to form two-dimensional layers. These two-dimensional layers are linked by interlayer hydrogen bonds, leading to the formation of a three-dimensional supramolecular network.

In the polymeric title complex, [Co(TBC)(BPE)(H2O)2] n [TBC is the 2,5-dicarboxybenzene-1,4-dicarboxylate dianion (C10H4O8) and BPE is 1,2-bis(4-pyridyl)ethene (C12H10N2)], the CoII ion, located on an inversion centre, assumes a distorted octahedral coordination geometry. The TBC and BPE ligands are located across individual inversion centres and bridge neighbouring CoII ions to form two-dimensional polymeric sheets.

In the title coordination polymer, {[Cd(C6H8O4S)(C13H14N2)]·H2O}n, the CdIIatom displays a distorted octahedral coordination, formed by three carboxylate O atoms and one S atom from three different 3,3′-thiodipropionate ligands, and two N atoms from two different 4,4′-(propane-1,3-diyl)dipyridine ligands. The CdIIcentres are bridged through carboxylate O atoms of 3,3′-thiodipropionate ligands and through N atoms of 4,4′-(propane-1,3-diyl)dipyridine ligands to form two different one-dimensional chains, which intersect to form a two-dimensional layer. These two-dimensional layers are linked by S atoms of 3,3′-thiodipropionate ligands from adjacent layers to form a three-dimensional network.

The title compound, [Co(C18H37N2)2(NCS)4], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabicyclo[2.2.2]octane (DABCO+) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octahedral coordination environment of the CoII ion is completed through four N atoms of isothiocyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C—H...N and C—H...S between the filamentous molecules lead to the formation of layers parallel to (001).

The title complex, [Co(C7H7N4O2)2(H2O)4], comprises mononuclear molecules consisting of a CoIIion, two deprotonated theophylline ligands (systematic name: 1,3-dimethyl-7H-purine-2,6-dione) and four coordinating water molecules. The CoIIatom lies on an inversion centre and has a slightly distorted octahedral coordination environment, with two N atoms of twotrans-oriented theophylline ligands and the O atoms of four water molecules. An intramolecular hydrogen bond stabilizes this conformation. A three-dimensional supramolecular network structure is formed by intermolecular O—H...O and O—H...N hydrogen bonds.

The crystal structures of two solvates offac-trichloridotris(trimethylphosphane-κP)rhodium(III) are reported,i.e.one with water in the crystal lattice,fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice,fac-[RhCl3(Me3P)3]·0.5CH3OH. These rhodium compounds exhibit distorted octahedral coordination spheres at the metal and are isotypic with the analogous iridium compounds previously reported by us [Merolaet al.(2013).Polyhedron,54, 67–73]. Comparison is made between the rhodium and iridium compounds, highlighting their isostructural relationships.
