“…On the other hand, the displacement of the Sb atom from the coordination plane (0.074 Å) is comparable to that found for the Pt(NO 2 phen)(ttcn) 2+ salt (0.084 Å). For comparison, we also have identified eight other structures of SbCl 5 2− salts in which none of the Cl atoms is involved in a bridging interaction with another Sb atom (i.e., isolated SbCl 5 2− units), and the Sb and axial Cl atoms show no evidence of approximately linear H-bonding or non-hydrogen contacts less than the sum of the van der Waals contacts where r Sb was assumed to be 1.6 Å. ,− For those structures, the average axial Sb−Cl distance is 2.376(17) Å, yet the equatorial Sb−Cl distances range from 2.43 to 2.97 Å. This seems to indicate that intermolecular interactions involving the equatorial Cl atoms have a somewhat limited effect on the axial Sb−Cl distance.…”

In the solid-state, the approximately square planar cation in orange crystals of [Pt(NO(2)phen)(ttcn)](PF(6))(2) (NO(2)phen = 5-nitro-1,10-phenanthroline; ttcn = 1,4,7-trithiacyclononane) has a short apical Pt...S(ttcn) distance (2.9415(15) A). In acetonitrile solution, the electronic spectrum shows a long-wavelength absorption band (412 nm; 2200 M(-1) cm(-1)), consistent with the notion that the axial Pt...S(ttcn) interactions stabilize states having metal-to-ligand charge-transfer (MLCT) character. Reaction with the hexachloroantimonate(V) salt of tris(4-bromophenyl)aminium (TBPA(+)) results in complex redox chemistry, involving the platinum complex, SbCl(5)(2-) and TBPA(+). In the case of Pt(bpy)(ttcn)(2+), orange-yellow crystals of [Pt(bpy)(ttcn)](2)(Sb(4)Cl(16)) were isolated from the reaction, whereas the reaction with Pt(NO(2)phen)(ttcn)(2+) consistently yielded red crystals of [Pt(NO(2)phen)(ttcn)](SbCl(5)) x 2 CH(3)CN. In the latter case, the geometry of the cation, including the apical Pt...S(ttcn) distance (2.9390(12) A), is very similar to that of the PF(6)(-) salt. However, the basal plane of each square pyramidal SbCl(5)(2-) opposes the nearly parallel coordination plane of an adjacent Pt(NO(2)phen)(ttcn)(2+) complex, resulting in an unusually short intermolecular Pt...Sb distance of 3.4259(3) A. The longest wavelength maximum in the diffuse reflectance spectrum and the solid-state emission maximum are shifted by approximately 1200 cm(-1) and approximately 700 cm(-1), respectively, to the red of those of the PF(6)(-) salt, consistent with perturbation of the complex's electronic structure because of the Pt...Sb interaction.

“…Until now most of the investigations were related to simple alkylammonium derivatives [5]. Diammonium cations received much less attention [6,7]. They differ from alkylammonium ions by having two ammonium groups, which are potentially capable of creating simultaneously N±H´´´X hydrogen bonds.…”

During the mixing of ethylenediammonium dichloride and antimony trichloride except of reported earlier [NH 3 (CH 2 ) 2 NH 3 ] 5 (Sb 2 Cl 11 ) 2´4 H 2 O a new salt [NH 3 (CH 2 ) 2 NH 3 ](SbCl 4 ) 2 was obtained. The crystals are monoclinic at 295 K, space group C2/m, a = 13.829(3), b = 7.408(1), c = 7.588(2) A Ê ; b = 103.18(3)°; V = 756.9(3) A Ê 3 ; Z = 2; d c = 2.585, d m = 2.56(2) g´cm ±3 . The structure consists of anionic sublattice built of Sb 2 Cl 8 2± units composed of two SbCl 5 2± square pyramids connected by edge. The ethylenediammonium cations are located in anionic cavities. The cations are disordered. Each methylene carbon atom is split between two positions. The X-ray diffraction, DSC, TGA and dilatometric methods were used to investigate properties of ethylenediammonium dichloride and its two salts with antimony trichloride. In [NH 3 (CH 2 ) 2 NH 3 ]Cl 2 one phase transition of first order and of the order-disorder type was found at 402 K. The [NH 3 (CH 2 ) 2 NH 3 ] 5 (Sb 2 Cl 11 ) 2´4 H 2 O undergoes one transition at 355 K which is accompanied by the dehydration of the sample. In [NH 3 (CH 2 ) 2 NH 3 ](SbCl 4 ) 2 two phase transitions of the order-disorder type: of first order at 238 K and of second order at 267 K were found. All those transitions in ethylenediammonium salts share common features. They were related to the changes in the molecular dynamics of ethylenediammonium cations. In the low temperature phases cations are ordered, while above T c they are characterised by overall reorientations along the axis passing through opposite nitrogen atoms.

Bei der Umsetzung von Ethylendiammoniumdichlorid mit Antimontrichlorid entsteht neben dem bekannten [NH 3 (CH 2 ) 2 NH 3 ] 5 (Sb 2 Cl 11 ) 2´4 H 2 O das neue Salz [NH 3 (CH 2 ) 2 NH 3 ](SbCl 4 ) 2 . Die Kristalle sind monoklin (295 K), Raumgruppe C2/m, a = 13,829(3), b = 7,408(1), c = 7,588(2) A Ê , b = 103,18(3)°, V = 756,9(3) A Ê 3 , Z = 2, d ber. = 2,585, d gef. = 2,56(2) g/cm 3 . Die Struktur besteht aus einem anionischen Teilgitter aus Sb 2 Cl 8 2± -Einheiten, die aus zwei quadratischen, u È ber eine Kante verbundenen Pyramiden SbCl 5 2± aufgebaut sind. Die Ethylendiammonium-Kationen sind in die anionischen Hohlra È umen eingelagert. Sie sind so fehlgeordnet, dass jedes CH 2 -Kohlenstoffatom eine von zwei Split-Positionen besetzt.Ro È ntgendiffraktometrie, DSC, TGA und dilatometrische Methoden wurden zur Untersuchung der Eigenschaften von Ethylendiammoniumdichlorid sowie der beiden genannten Salze mit SbCl 3 herangezogen. In [NH 3 (CH 2 ) 2 NH 3 ]Cl 2 wurde ein Phasenu È bergang erster Ordnung vom ¹order-disorderª-Typ bei 402 K gefunden. [NH 3 (CH 2 ) 2 NH 3 ] 5 -(Sb 2 Cl 11 ) 2´4 H 2 O zeigt eine Phasenumwandlung bei 355 K, die mit der Dehydratisierung verbunden ist. Beim [NH 3 (CH 2 ) 2 NH 3 ](SbCl 4 ) werden zwei Phasenu È berga È nge vom order-disorder-Typ gefunden: einer erster Ordnung bei 238 K und einer zweiter...
