Synthesis, crystal structure and Hirshfeld surface analysis of the tetra-kis complex NaNdPyr 4 ( i -PrOH) 2 · i -PrOH with a carbacyl-amido-phosphate of the amide type.

The tetra-kis complex of neodymium(III), tetra-kis-{μ- N -[bis-(pyrrolidin-1-yl)phos-phor-yl]acet-am-id-ato}bis(pro-pan-2-ol)neodymiumsodium pro-pan-2-ol monosol-vate, [NaNd(C 10 H 16 Cl 3 N 3 O 2 ) 4 (C 3 H 8 O) 2 ]·C 3 H 8 O or NaNdPyr 4 ( i -PrOH) 2 · i -PrOH, with the amide type CAPh ligand bis( N , N -tetra-methylene)(tri-chloro-acetyl)phos-phoric acid tri-amide (HPyr), has been synthesized, crystallized and characterized by X-ray diffraction. The complex does not have the tetra-kis-(CAPh)lanthanide anion, which is typical for ester-type CAPh-based coordin-ation compounds. Instead, the NdO 8 polyhedron is formed by one oxygen atom of a 2-propanol mol-ecule and seven oxygen atoms of CAPh ligands in the title compound. Three CAPh ligands are coordinated in a bidentate chelating manner to the Nd III ion and simultaneously binding the sodium cation by μ 2 -bridging PO and CO groups while the fourth CAPh ligand is coordinated to the sodium cation in a bidentate chelating manner and, due to the μ 2 -bridging function of the PO group, also binds the neodymium ion.
