title: Synthesis and structural characterization of rhenium(I) tricarbonyl complexes with the bidentate ligands o-(diphenylphosphino)benzaldehyde (P∩O) and o-[(diphenylphosphino)benzylidene]analine (P∩N).
abstract: A series of rhenium(I) tricarbonyl complexes with bidentate P,O donor ligand o-(diphenylphosphino)benzaldehyde (P∩O) and its Schiff base P,N donor ligand o-[diphenylphosphino)benzylidene]analine (P∩N) have been synthesized and structurally characterized. All the complexes of the type [ReX(CO)(3)(LL)] (where LL = P∩O, P∩N) reveal a distorted octahedral structure with the three carbonyl ligands arranged in the facial fashion. Crystal data for 1, C(22)H(15)ClO(4)PRe·1/2C(6)H(14): triclinic, P1, a=8.7430(4), b=9.5767(4), c=13.9449(6) Å, α=93.651(1), β=101.265(1), γ=93.048(1); V=1140.20(9) Å(3), Z=2.2, C(22)H(15)BrO(4)Pre: monoclinic, C2/c, a=31.6800(16), b=8.8880(4), c=18.4517(9) Å, β=124.990(1); V=4256.4(4) Å(3), Z=8. 3, C(28)H(20)ClNO(3)Pre: monoclinic, C2/c, a=22.675(4), b=8.803(2), c=28.218(5) Å, β=100.192(3); V=5543.5(16) Å(3), Z=8.4, C(28)H(20)BrNO(3)Pre: monoclinic, C2/c, a=23.035(1), b=8.7561(4), c=28.269(1) Å, β=100.811(1); V=5600.4(5) Å(3), Z=8.
