Bis(nitrilo)tris(methylenephosphonato)dodecaaquatrihydrohexasodium Europium(III) [EuNa6H3(H2O)12{N(CH2PO3)3}2]: Synthesis and Structure

Magnetic Behavior of Light Lanthanide (La–Tb) in Linear‐Chain Nitrilo‐Tris‐Methylenephosphonates with Different Structures

“…The [Ln NTP H 3 ]·1.5H 2 O (I‐Ln) and [Ln NTP 2 Na 6 H(H 2 O) 10 ]· n H 2 O[Na(H 2 O) 6 ] 2 (II‐Ln) compounds were obtained according to refs. [32,34–39]. The resulting crystals were separated, washed with DMSO, diethyl ether, and dried in air.…”

The Structure of the Dipolar Bond in the Rare Earth Nitrilotris(Methylene Phosphonate)s with Different Oxygen Coordination Symmetries

“…Synthesis and isolation of compounds I – V were performed using the techniques described in Refs . Testing of the samples employed was carried out using powder X‐ray diffraction (PXRD) and elemental analysis.…”

“…The single‐crystal X‐ray diffraction (XRD) analysis of compounds II , III and V was described in Refs . and provided as Supporting Information.…”

“…When the Eu 3+ ion interacts with NTP under the same conditions, the complex [EuNa 6 H 3 (H 2 O) 12 {N(CH 2 PO 3 ) 3 } 2 ] ( III ) with absolutely different structure is formed: the coordination polyhedron of an Eu 3+ ion is a distorted trigonal‐dodecahedron (Figure , structure III ).…”

“…At two rhombohedron vertices remote from the RE atom there are N atoms, and at the six nearest vertices oxygen atoms are located (Figure , structure II ). The complexes of praseodymium, neodymium, samarium, terbium and gadolinium have similar structure.…”
