Complexes of salicylaldehyde and related ligands with beryllium(II) ion. X-ray crystal structures of bis( N-isopropylsalicylaldiminato) beryllium(II) and bis( N-phenylsalicylaldiminato)beryllium(II)

Abstract

By reaction of BeSO 4 with salicylaldehyde and related salicylaldimines the complexes [Be(Sal)(OH)] ∞, [Be(Sal) 2], [Be(Sal–NH) 2], [Be(Sal–N–R) 2] (R= i-Pr, Ph) were obtained. X-ray structure determinations have been carried out on the [Be(Sal–N–R) 2] (R= i-Pr ( 1), Ph ( 2)) compounds. Crystal data for 1: orthorhombic, space group Pbca, a=19.665(5), b=15.030(6), c=12.801(2) Å, Z=8. Crystal data for 2: orthorhombic, space group P2 12 12 1, a=14.430(5), b=16.760(5), c=17.607(5) Å, Z=8. In both the structures the beryllium center displays a slightly distorted tetrahedral environment, being linked to the oxygen and nitrogen atoms from two salicylaldiminato ligands.
