Bis-Hexaaquasodium Decaaqua-Monohydrogen-Hexasodium-Gadolinium-bis-(Nitrilo-Tris-Methylenephosphonate) Tetrahydrate: Synthesis, Structure, Chemical Bonding

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.…”

“…In these compounds, the Ln atom was coordinated by two completely deprotonated NTP molecules and was surrounded by an elongated rhombohedron whose two vertices far from the RE atom contained nitrogen atoms, and six nearest vertices contained oxygen atoms (Figure 1b). [34][35][36][37][38] Interaction of the deprotonated NTP with Eu under the same conditions formed a [Eu NTP 2 Na 6 H 3 (H 2 O) 12 ] complex with a completely different structure: the Eu coordination polyhedron was a distorted trigon dodecahedron; therefore, this complex was not considered in this work.…”

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.…”

“…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.…”
