Synthesis and crystal structure of iodo-1-(2′-aminophenyl)-2,6-diaza-6-methyl-9-amino-1-noneno copper(II) iodide
摘要:
Reaction of equimolar amounts of 2-aminobenzaldehyde and 3,3'-diamino-N-methyldipropylamine in methanol affords a novel 1:1 condensation product, abaMedpt, which has been isolated as the copper(II) complex, [Cu(abaMedpt)I]I. The crystal structure of the complex has been determined from single crystal diffractometer data and refined to a final R factor of 0.0353 with 2492 unique observations and 206 variables. The complex crystallizes in the monoclinic space group P2l/c (N-degrees-14) with a = 9.263(2), b = 18.189(3), c = 11.740(3) angstron, beta = 92.97(4)-degrees, Z = 4, D(c) = 1.902 g cm-3. The structure involves a five-coordinate square-pyramid CuN4I chromophore and an uncoordinated iodide anion. Nitrogen atoms constitute the basal plane, while the bonded iodine occupies the apical position. The structure contrasts with the more usual distorted trigonal-bipyramidal stereochemistries of CuN4I chromophores reported so far.
