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.
