“…The aqua-chloride complexes have been chosen as starting building blocks to avoid the formation of polymeric chains. Previously we have reported a series of cobalt(III) dioximates containing Cl – and Br – or N 3 – anions and various polyfunctional ligands, derivatives of sulfanilamide and isonicotinic hydrazide, which coordinate to the metal in monodentate mode with the formation of mononuclear complexes. , …”

Three binuclear and one mononuclear cobalt-(III) dioximates with the compositions [Co 2 (dmgH) 4 (bpy)-Cl 2 ]•1.5dmf (1), [Co 2 (nioxH) 4 (bpy)Cl 2 ]•0.5H 2 O (2), [Co 2 (dmgH) 4 (bpe)Cl 2 ]•0.5H 2 O (3), and [Co(dmgH) 2 (bpy)-Cl]•H 2 O (4) (where dmgH 2 = dimethylglyoxime, nioxH 2 = 1,2-cyclohexanedionedioxime, bpy = 4,4′-bipyridine, bpe = 1,2bis(4-pyridyl)ethane, and dmf = N,N-dimethylformamide)were prepared by replacement of water molecule in Co(III) mononuclear dioximates by bpy and bpe ligands. All compounds were characterized by single-crystal X-ray diffraction and spectroscopic techniques. In all complexes Co(III) atoms have an identical octahedral N 5 Cl environment formulated by four nitrogen atoms of two mono-deprotonated oxime ligands in a square planar mode, and the nitrogen atom of the bpy/bpe molecules and chloride atom in the axial positions. In 1−3 bpy/bpe exobidentate spacer ligands serve as bridging "rods" and unite two planar cobalt(III) bis-dioximates in binuclear complex with wheel-and-axle topology. The packing of bulky binuclear complexes results in formation of porous structure with hourglass-like channels of diameter ca. 0.6−1.3 nm in the crystal of compound 1 and smaller cavities in 2. The sorption properties for 1 were also measured. The π•••π stacking interaction between monodentate bpy ligands of mononuclear complexes 4 emulate supramolecular binuclear assembly with wheel-and-axle topology.

Abstract:The interaction of [Fe(DfgH) 2 Py 2 ] (where DfgH=monodeprotonated diphenylglyioxime, Py-pyridine) and 1,3,5-triazine (Trz) in chloroform resulted in a new coordination compound with the composition [Fe(DfgH) 2 (Trz) 2 ]·2CHCl 3 (1). The crystal structure of 1, determined by single crystal X-ray diffraction, revealed that Fe(II) atom is coordinated by four oximic nitrogen atoms of two DfgH and two nitrogen atoms of two Trz ligands resulting in octahedral surrounding.Keywords: synthesis; Fe(II)dioximate; 1,3,5-triazine, crystal structure IntroductionThe inner-sphere substitution of apical ligands in [M(DioxH) 2 А 2 ] complexes (M = metal ion, DioxH = monodeprotonated α-dioxime and A = neutral apical ligand) represents an attractive procedure for obtaining new complexes with polyfunctional ligands such as bridgind exo-bidentate or polydentate species. Aromatic [1] and heterocyclic [2,3] amines, thio-and seleno-carbamides [4, 5] readily enter the inner coordination sphere of dioximates. Generally, such compounds reveal an octahedral surrounding of the metal ion with a stable square-planar M(DioxH) 2 building block consolidated by two strong intramolecular hydrogen О-Н···О bonds [6]. Various binuclear and polymeric coordination compounds based on Co(III), Cu(II), Cd(II) and Zn(II) dioximates and 4,4'-bipyridyl bridging ligands have been reported [7][8][9][10]. It was of particular interest to investigate the complexation process and coordination ability of potentially polydentate heterocyclic amines, in particular, 1,3,5-triazine (Trz). The CSD [11] statistics indicates that the architecture of the molecule Trz, which contains three donor nitrogen atoms, facilitates the formation of polynuclear complexes, three-dimensional networks, various nanoporous materials with Cu(II) [12][13][14], Ru(II) [15, 16], Pt(II) [17] and Ag(I) [18, 19] 3 (1) and X-ray study of these crystals.
