catena-Poly[[bis­(μ-2-formyl-6-meth­oxy­phenolato-1:2κ⁴O¹,O⁶:O¹,O²)copper(II)sodium]-μ-tetra­fluorido­borate-1:1′κ²F:F′]

In the title heterodinuclear complex, [CuNa(BF₄)(C₈H₇O₃)₂]_n, the Cu^II ion is four-coordinated by four O atoms of two 2-formyl-6-meth­oxy­phenolate ligands, giving rise to a square-planar geometry. The Na⁺ ion is six-coordinated by four O atoms from the two ligands and two F atoms of two tetra­fluoridoborate anions. The tetra­fluoridoborate anion links the Na⁺ ions, forming a one-dimensional structure along [001]. Three F atoms of the tetra­fluoridoborate anion are disordered over two sets of sites, with an occupancy ratio of 0.790 (11):0.210 (11).

catena-Poly[copper(II)-bis­(μ-2-formyl-6-meth­oxy­phenolato-κ⁴O²,O¹:O¹,O⁶)-[(methanol-κO)sodium]-μ-perchlorato-κ²O:O′]

In the title heterodinuclear complex, [CuNa(C₈H₇O₃)₂(ClO₄)(CH₃OH)]_n, the Cu^II ion is five-coordinated by four O atoms from two 2-formyl-6-meth­oxy­phenolate anions and one O atom from a perchlorate anion in a distorted square-pyramidal geometry. The Na⁺ ion is six-coordinated by four O atoms from two 2-formyl-6-meth­oxy­phenolate ligands, one O atom of a methanol mol­ecule and one O atom of a perchlorate anion. The perchlorate anions link the Na⁺ and Cu^II ions, forming a chain along [010]. O—H...O hydrogen bonds connect the chains. π–π inter­actions are present between the benzene rings [centroid–centroid distances = 3.566 (2) and 3.702 (2) Å]. The O atoms of the perchlorate anion are disordered over two sets of sites, with an occupancy ratio of 0.481 (8):0.519 (8).
