Synthesis and Structural Features of Hydrogen-Bonded Networks Based on The Combination of Tectons Triphenylboroxine Cation and Pt(SCN)4 Anion Salts

Abstract

In this work, a new compound [C 15 H 16 B 3 N 3 O 5 ].[Pt(SCN) 4 ].2(H 2 O] (1) has been synthesized and structurally characterized. The compound (1) crystallizes in monoclinic, space group P2 1 /c a=10.443 Å, b= 24.918 Å, c= 15.048 Å, =90  , β=133.945  , γ=90  , V=2819.4 Å 3 , Z=4. The use of molecular tecton (building block) able to form thiocyano-based hydrogen-bonded synthons (OH•••SCN) to synthesize a diverse range of crystal structures is described. In the crystal structure, molecules are linked by intermolecular SCN•••HN and BO•••HN hydrogen bonds, forming a threedimensional network.

Inducing Platinophilic Interactions in [Pt(SCN)4]2– Salts by Cation Tuning

“…Tetrathiocyanatoplatinate­(II), [Pt­(SCN) 4 ] 2– , an analogue of tetracyanoplatinate, has been underutilized in supramolecular chemistry. − Despite the similarity to [Pt­(CN) 4 ] 2– , no platinophilic interactions have been observed in any simple structures with [Pt­(SCN) 4 ] 2– units or any [Pt­(SCN) 4 ] 2– -based coordination polymer materials. Simple salts incorporating [Pt­(SCN) 4 ] 2– , such as with [ n Bu 4 N] + and [Mn­(terpy) 2 ] 2+ cations, display packing where the Pt­(II) centers are separated from each other by over 8 Å. , Coordination polymers and clusters have also been synthesized by pairing [Pt­(SCN) 4 ] 2– with [Zn­(2,2′-bipyridine) 2 ] 2+ and [Cu­(μ–OH)­(tetramethylethylenediamine)] 2 2+ , producing 1D chains with no platinophilic interactions. , One of the closest reported Pt–Pt distances between [Pt­(SCN) 4 ] 2– units is found in the simple salt [Acridinium] 2 [Pt­(SCN) 4 ], but the distance is still a very long 6.836 Å …”
