“…The [Pt(SCN) 4 ] 2– anion is comparable to [Pt(CN) 4 ] 2– in the sense that it can bridge up to four metal centers via the four thiocyanate species and thus increase the dimensionality of the resulting coordination polymer. However, the SCN – unit coordinates at an angle of approximately 50–70° to the Pt(II) center, as opposed to the strictly linear coordination for the analogous CN – species. − …”

New complexes and the first coordination polymers containing [Pt(SCN)4](2-) of the type [M(L)x][Pt(SCN)4] (where L = 2,2'-bipyridine (bipy), x = 2, M = Co(II), Ni(II), Cu(II); L = ethylenediamine (en), x = 2, M = Ni(II), Cu(II); L = N,N,N',N'-tetramethylethylenediamine (tmeda), x = 1, M = Cu(II); L = 2,2';6',2″-terpyridine (terpy), x = 1, M = Mn(II), Co(II); L = 1,10-phenanthroline (phen), x = 2, M = Pb(II)) were prepared by reacting the appropriate metal-ligand cations with K2[Pt(SCN)4] and structurally characterized. [M(bipy)2Pt(SCN)4]2·2MeOH (M = Co (1), Cu (4)) consist of supramolecular tetranuclear distorted squares containing two [M(bipy)2](2+) and two [Pt(SCN)4](2+) units. [Cu(bipy)2(NCS)]2[Pt(SCN)4] (6) is a double salt of the [Pt(SCN)4](2-) anion and two [Cu(bipy)(NCS)](+) cations. [Cu(en)2Pt(SCN)4] (7, 8) are 1-D coordination polymers that are coordinated in either cis or trans fashion at the [Pt(SCN)4](2-) unit, for 7 and 8, respectively. Complexes [Cu(en)2Pt(SeCN)4] (9) and [Ni(en)2Pt(SCN)4] (10) are similar to 8 and 7, respectively, but complex 9 (prepared using ((n)Bu4N)2[Pt(SeCN)4]) also presents intermolecular Se-Se interactions which resulted in an increased dimensionality. Compounds [M(terpy)Pt(SCN)4] (M = Mn (11), Co (13)) involve 2-D sheets of [M(terpy)](2+) and [Pt(SCN)4](2-) units, whereas [Mn(terpy)2][Pt(SCN)4] (12) is a double salt of one [Mn(terpy)2](2+) unit and one [Pt(SCN)4](2-). [Cu(tmeda)Pt(SCN)4] (14) contains a five-coordinate Cu(2+) metal center coordinated to one tmeda ligand and three different [Pt(SCN)4](2-) units, resulting in 2-D sheets. [Pb(phen)2Pt(SCN)4] (15) contains an 8-coordinate Pb(2+) metal center coordinated to two phen ligands and four [Pt(SCN)4](2-), generating a 3-D network in the solid state. Structural correlations were established between the ancillary ligand, the choice of metal, the structure of the [Pt(SCN)4](2-) building block, and the resulting dimensionality of the coordination polymers.

“…46,56 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. 49 With the evidence that hydrogen bonding interactions from cations can induce Au−Au interactions in [Au(CN) 2 ] − and related species such as [Au 2 (i-mnt) 2 ], 57,58 herein we apply this principle to the more difficult challenge of inducing Pt−Pt interactions in [Pt(SCN) 4 ] 2− . Compared to [Au(CN) 2 ] − , dianionic [Pt(SCN) 4 ] 2− units have higher Coulombic repulsion.…”

“…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 …”

Five Cu(II) hydroxo-bridged complexes of the type [Cu2(μ-OH)2(L)2][A]x·yH2O (where L = 1,10-phenanthroline, A = NCS–, x = 2, y = 2 (1); L = 2,2′-bipyridine, A = NCS–, x = 2, y = 1 (2); L = 2,2′-bipyridine, A = [Au(CN)4]–, x = 2, y = 0 (3) and 2 (4); L = N,N,N′,N′-teteramethylethylenediamine, A = [Pt(SCN)4]2–, x = 1, y = 0 (5)) have been prepared and have been characterized by elemental analysis, IR and Raman spectroscopy, X-ray crystallography, and SQUID magnetometry. Complexes 1 and 2 consist of five-coordinate Cu(II) hydroxo-bridged dinuclear units bound to two NCS– anions in the apical positions, 3 and 4 are pseudo-polymorphs of a Cu(II) hydroxo-bridged dimer core with [Au(CN)4]– counteranions, and 5 is a coordination polymer of Cu(II) hydroxo-bridged dimers with trans-bridging [Pt(SCN)4]2– anions coordinated in the apical position of the five-coordinate Cu(II) centres. The magnetic susceptibility versus temperature for each system was measured, fit to obtain J-coupling values (which range from –0.37 to 17.8 cm−1), and qualitatively compared to known magnetostructural correlation parameters.
