Synthesis and Structure of a Molecular Zinc Phosphate [(C₁₂H₈N₂Zn)₂(HPO₄)(H₂PO₄)₂]

Abstract

A hydrothermal reaction of a mixture of ZnCO 3 , phosphoric acid, 1,10-phenanthroline in H 2 O gave rise to large plates of a new zinc phosphate, [(C 12 H 8 N 2 Zn) 2 (HPO 4 )(H 2 PO 4 ) 2 ], I. The structure consists of ZnO 3 N 2 distorted trigonal-bipyramidal and PO 4 tetrahedral units linked through their vertices to give rise to a zero-dimensional molecular solid (monomer). The structure of the monomer appears to be similar to the secondary building unit (SBU) 4 ϭ1, commonly found in many fibrous zeolites. To our knowledge, this is the first time this building unit has been isolated. The structure, with a unique composition, is stabilized by hydrogen Synthese und Struktur eines molekularen ZinkphosphatsInhaltsübersicht. Durch hydrothermale Reaktion vonZnCO 3 , Phosphorsäure und 1,10-Phenanthrolin in H 2 O wurden große Plättchen eines neuen Zinkphosphats [(C 12 H 8 N 2 Zn) 2 (HPO 4 )(H 2 PO 4 ) 2 ](I) erhalten. Die Struktur besteht aus verzerrt-trigonal-bipyramidalen ZnO 3 N 2 -und tetraedrischen PO 4 -Einheiten, die über Ecken zu einer monomeren Struktur verbunden sind. Die Struktur erscheint ähnlich zur sekundären Baueinheit (SBU) 4 ϭ1 zu sein, die gewöhnlich in vielen faserigen Zeoliten gefunden wird. Nach unserer Kenntnis ist diese Baueinheit hier zum ersten Mal isoliert worden.

The molecular structure of the title compound, (I), which is isostructural with the previously reported zinc analogue (Ganesan et al, 2003) is illustrated in Fig 1. It consists of distorted trigonal-bipyramidal MnO 3 N 2 and tetrahedral PO 4 units. The Mn(II) cation is five coordinated by three oxygen and two nitrogen atoms, with Mn-O distances in of 2.039 2-2.088 (1) Å and Mn-N distances in the range 2.250 (2)-2.281 (2) Å.…”

“…The packing arrangement shows that there are π–π stacking interactions existing between the adjacent phenanthroline rings (<3.5 Å) (Figure S1, Supporting Information). Compound 2 crystallizes in the space group Fdd 2. , It features an isolated cluster structure with one [Zn 2 (HPO 4 )­(H 2 PO 4 ) 2 ] unit and two coordinated phenanthroline ligands (Figure ). The Zn atom is five coordinated with two nitrogen and three oxygen atoms to form a distorted trigonal bipyramidal unit.…”
