Synthesis, crystal structure and Hirshfeld surface analysis of the tetrakis complex NaNdPyr4(i-PrOH)2·i-PrOH with a carbacylamidophosphate of the amide type

The tetrakis complex of neodymium(III), tetrakis{μ- N -[bis(pyrrolidin-1-yl)phosphoryl]acetamidato}bis(propan-2-ol)neodymiumsodium propan-2-ol monosolvate, [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 -tetramethylene)(trichloroacetyl)phosphoric acid triamide (HPyr), has been synthesized, crystallized and characterized by X-ray diffraction. The complex does not have the tetrakis(CAPh)lanthanide anion, which is typical for ester-type CAPh-based coordination compounds. Instead, the NdO 8 polyhedron is formed by one oxygen atom of a 2-propanol molecule 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.
