AI Article Synopsis

  • The compound is a copper complex with the formula [Cu(C(11)H(10)N(2)O(2))(2)](BF(4))(2)·2H(2)O, obtained from a specific molar mixture involving copper(II) tetra-fluoridoborate and di-2-pyridyl ketone.
  • The complex has a centrosymmetric structure, with its cation similar to known structures but shows a distortion in its geometry, where the Cu-O bonds deviate by 25 degrees from the ideal octahedral shape.
  • Additionally, the BF(4)(-) anion displays disorder in its fluorine atoms, occurring in two different configurations with a noted statistical ratio.

Article Abstract

The title complex, [Cu(C(11)H(10)N(2)O(2))(2)](BF(4))(2)·2H(2)O, was isolated as a dihydrate from a 1:2 molar mixture of copper(II) tetra-fluoridoborate hexa-hydrate with di-2-pyridyl ketone in aqueous solution. The centrosymmetric complex cation is structurally similar to that found in previously reported salts and exhibits Cu-O bonds deviating by 25 degrees from an octa-hedral geometry by the so-called 'off-axis angle' distortion. The BF(4) (-) anion exhibits a two site disorder of the fluorine atoms [ratio 0.210 (8):0.790 (8)].

The crystal structure of a platinum(II) supra-molecular building block, [Pt(dbbpy)(NCCH)](BF) (dbbpy = 4,4'-di--butyl-2,2'-bi-pyridine, CHN) is an example of a rare head-to-head dimer, even with the bulky -butyl groups of the bi-pyridine. This packing motif still enables significant π-π inter-actions between two pyridyl groups, and may result from the close proximity of the tetra-fluorido-borate ions to the platinum(II) complexes, resulting in intra-molecular H⋯F distances between 2.156 and 2.

The complex shows a distorted octa-hedral environment around the Cu cation (site symmetry 2) and adopts the centrosymmetric space group 2/. The presence of the 6-methyl substituent hinders the approach of the pyridine group to the Cu core.

In the structure of the title salt, [Co(C6H6N2)2(H2O)2](BF4)2, the Co(II) atom is located on an inversion centre. The transition metal is in a slightly distorted octa-hedral coordination environment, defined by the cyano N atoms of four hex-3-enedi-nitrile ligands in equatorial positions and the O atoms of two water mol-ecules in axial positions. The bridging mode of the hex-3-enedi-nitrile ligands leads to the formation of cationic chains extending parallel to [1-10].
