The compound was prepared according to the literature method (Kido et al., 2003), and recrystallization from methanol afforded violet, block-shaped crystals.
The H atoms bound to C atoms were placed in caculated positions with C—H = 0.93–0.77 Å and included in the refinement with Uiso(H) = 1.2Ueq(C). The H atom attached to the methanol O atom were found from E-map, and was fixed with O—H = 0.85 Å and refined isotropically.
1-(2-hydroxybenzamido)-2-(2-hydroxy-3-methoxybenzylideneamino)ethane, abbreviated as H3L, is an excellent bridging ligand that can link two metal atoms via the phenolato and the amido oxgen atoms to form polynuclear complexes (Kido et al., 2000). A few cyclic heterometallic tetranuclear complexes have been synthesize and their structures have been characterized by diffraction analysis and magnetic studies (Hamamatsu et al., 2007; Kido et al., 2003; Osa et al., 2003). The syntheses requires K[CuL] as the starting reactant. This compound crystallizes from methanol as the title compound.
The structure consists of [CuL]- and [K(MeOH)]+ moieties connected by the phenolato and amido oxygen atoms (Fig. 1). The coordination geometry of potassium is an octahedron, and that of copper is a square plane. Two N atoms and two O atoms are linked to the copper atom. The coordination environment is similar to those found in other cyclic heterometallic tetranuclear complexes.
The phenolato oxygen and amido oxgen atoms are involving in bridging to form a ladder structure (Fig. 2). Adjacent ladders are further linked by hydrogen bonds (involving the amido group and the methanol molecule) (O···O 2.702 (4) Å) to form a two-dimensional, hydrogen-bonded network.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

1-(2-hydroxybenzamido)-2-(2-hydroxy-3-methoxybenzylideneamino)ethane, abbreviated as H3L, is an excellent bridging ligand that can link two metal atoms via the phenolato and the amido oxgen atoms to form polynuclear complexes (Kido et al., 2000). A few cyclic heterometallic tetranuclear complexes have been synthesize and their structures have been characterized by diffraction analysis and magnetic studies (Hamamatsu et al., 2007; Kido et al., 2003; Osa et al., 2003). The syntheses requires K[CuL] as the starting reactant. This compound crystallizes from methanol as the title compound.
The structure consists of [CuL]- and [K(MeOH)]+ moieties connected by the phenolato and amido oxygen atoms (Fig. 1). The coordination geometry of potassium is an octahedron, and that of copper is a square plane. Two N atoms and two O atoms are linked to the copper atom. The coordination environment is similar to those found in other cyclic heterometallic tetranuclear complexes.
The phenolato oxygen and amido oxgen atoms are involving in bridging to form a ladder structure (Fig. 2). Adjacent ladders are further linked by hydrogen bonds (involving the amido group and the methanol molecule) (O···O 2.702 (4) Å) to form a two-dimensional, hydrogen-bonded network.
