Source of materialCobalt(II) acetate, equimolar 4-methyl-1,4,7-triazaheptane and two equivalent molar salicylaldehyde were dissolved in methanol and mixed together. The clear pink solution gradually got dark red. It was stood still in air for one week. Large cubic crystals were precipitated. They were filtered and washed with methanol and dried in air (yield 68 %). DiscussionCobalt is an important life-required element. Many cobalt(II,III) complexes were prepared and structurally determined by single X-ray analysis [1][2][3][4][5][6][7]. Especially, complexes with various Schiff bases are a hot branch of cobalt chemistry [1,2,4,6,7]. The title compound is a discrete mononuclear cobalt(III) complex. The central cobalt(III) atom is five-coordinated by three oxygen atoms and two nitrogen atoms from one tetradentate diSchiff base ligand and one unidentate acetate anion. The metal is in a distorted square-pyramidal environment with the oxygen atom from the acetate situated in the apical position and the four donors from the Schiff base constituting the basal plane. The mean deviation of the basal plane is 0.151(2) Å, and the central cobalt(III) is 0.131(2) Å above the plane towards the apical oxygen atom. The dihedral angles between the Co basal plane and the two benzene rings in the Schiff base are 36.3(2)°and 28.2(2)°, and the two aromatic rings are at the angle of 64

“…The mononuclear chromium(III) complex (Fig. 1) has a structure similar to that found for the cobalt(III) analogue (Zhu et al, 2003), and comprises a complex cation and Cl À anion. In the cation, the central atom is six-coordinated by four N and two O atoms derived from the two Schiff base ligands, forming a slightly distorted octahedron.…”

“…Schiff bases obtained by condensation of N-2-hydroxyethylaminoethylamine and salicylaldehyde or analogues (L) have strong coordination abilities to transition metal ions. Recently, many such metal complexes have been structurally characterised: zinc(II) (Usman et al, 2003;You et al, 2004), cobalt(III) (Zhu et al, 2003), silver(I) (Zhu et al, 2000;, copper(II) (Qu et al, 2004), nickel(II) (Ma et al, 2005) and cadmium(II) (Yang et al, 2004). However, no reports on related chromium(III) complexes have appeared.…”

Ci8Hi8.50AgFN4O7.25, monoclinic, C12/cl (no. 15), a = 23.65(1) A, b = 5.524(2) A, c = 31.13(1) A, P = 98.564(7)°, V = 4022.4 A 3 , Z = 8, R gl (F) = 0.056, wRniF 2 -) = 0.170, T= 298 K. Source of materialAll reagents and solvents were used as purchased without further purification. C, H and N elemental analyses were performed on a Perkin-Elmer elemental analyzer. Equimolar 2-fluorobenzaldehyde (1 mmol, 124 mg) and 2-hydroxyaminoethylamine (1 mmol, 104 mg) were dissolved in ethanol solution (5 ml) with stirring. After 30 min, a suspension solution of Ag20 (166 mg, 0.5 mmol) and 3,5-dinitrobenzoic acid (212 mg, 1 mmol) in acetonitrile (10 ml) were added to the above solution. The resultant solution was kept to evaporate slowly in air. After about half of the solvent had evaporated, large colorless slab crystals of the title compound were deposited and were collected by filtration (yield 61 %). Elemental analysis: found -C,40.10%;H, 3.55 %;N, 10.26 %;calc. forCi8Hi8.5AgFN4O7.25-C, 40.51 %; H, 3.49 %; N, 10.50 %. Experimental detailsAll atoms were fixed geometrically and restrained to ride on their parent atoms. They were treated as riding atoms, with [/¡¡»(H) = 1.2U e q(C, N) and i/i S0 (H) = 1.5t/eq(0), respectively. The disordered water 08 and O8A positions are disordered and half occupied. This is coupled with the orientational disorder of the ethoxy group. All disordered atoms were refined using restrained bond distances and angles. Only uniform isotropic displacement parameters could be assigned to the respective non-hydrogen atoms.In the last refinement cycles the s.o.f. s of the disordered ethoxy atoms were fixed to 0.5 due to their ranging between 0.45 and 0.63 in previous refinement stages. The crystals turn to fragile even to powder (decomposes) at a temperature below 120 K, thus a data collection at low temperature was not possible. At the present condition, the U values of a few atoms are reasonably large. DiscussionRecently we prepared some new Schiff bases using N-2-hydroxyethyl-l,2-ethylenediamine and aldehydes, and some new transition metal complexes [1][2][3][4][5] with Schiff bases. In this paper we reported the crystal structure of a silver® complex with a new Schiff base ligand, A^-(2-(2-hydroxyethylamino)ethyl)-2-fluorobenzaldimine (L). The crystal structure of the title compound consists of a neutral mononuclear silver(I) complex and lattice water molecules. The 08 and 08 A atoms of the lattice water locate in special positions. In the complex, the central silver(I) complex is three-coordinated by two nitrogen atoms from a Schiff base ligand, and by one oxygen atom from a 3,5-dinitrobenzoate anion. The 3,5-dinitrobenzoate acts as a monodentate ligand. The Ag-O bond length is 2.157(4) A, being significantly shorter than that of 2.483(3) A in other silver(I) complexes with 3,5-dinitrobenzoate [6], but being in the range of normal Ag-O contacts. The Ag-Nimine bond length (2.574(5) A) is much longer than the Ag-Namine bond length (2.229(5) A), which is unusual. This is presumably caused by...
