Synthesis and crystal structure of bis-[co(l)‎(NCS)‎(MEOh)‎], where(lh = 4-(salicylaldimine)‎ antipyrine)‎

Abstract EN

The title complex was isolated as red solid material from the reaction of Co (SCN)2 with 4-(Salicylaldimine) antipyrine in ethanol.

The molecular structure has been determined by elemental analysis, FTIR, UV-Vis and X-ray diffraction.

The crystallographic data are: monoclinic P21/n, a = 9.8335(3) Å, b = 18.8593(6) Å, c = 11.2921(4) Å, α = 90°, β = 102.880(2)˚, γ = 90°, V =2041.46(12) Å3 and Z = 2, R =0.045.

The dicobalt (II) complex is Centro symmetric dimer in which the Co(II) ions are six coordinate being bonded to three coordinating donor sites from the corresponding tridentate Schiff base ligand and the fourth one is relatively bonded by phenolic oxygen, the fifth and sixth donor sites comes from isothiocyanate and methanol.
