“…Instead, the intermediary (PPN) 2 Ge(CN) x Cl y was converted in the second step to (PPN) 2 Ge(CN) 6 (2) by applying a large excess of NaCN instead of (PPN)CN and a longer reaction time (196 h). It was found that AgCN is not suitable as a CN-ligand transfer reagent since the crystallization from the solution containing (PPN) 2 Ge(CN) x Cl y and AgCN removes the PPN cation as part of the silver salt (PPN)Ag(CN) 2 , 28 which was identified by single crystal XRD (see the Supporting Information, p 29). This reaction is also likely to occur if AgCN is used in syntheses of the Si and Sn analogs 1 and 3.…”

The rare octahedral EC6 coordination skeleton type is unknown for complexes with coordination centers consisting of Group 14 elements. Here, the first examples of such EC6 species, the hexacoordinate homoleptic cyanido complexes E(CN)6 2− , E = Si, Ge, Sn, have been synthesized from element halides SiCl4, GeCl4 and SnF4 and isolated as salts with PPN counter ions (PPN + = (Ph3P)2N + ) on a scale 0.2-1 g. Characterization by spectroscopic techniques and by structure determination through single crystal crystallographic methods show that these pseudohalogen complexes have effective octahedral symmetry in solution and in the solid state.Infrared spectra obtained in solution reveal that the T1u symmetric IR-active vibrations in all three complexes have unusually small oscillator strengths. The observed reluctance of Si(CN)6 2− , Ge(CN)6 2− and Sn(CN)6 2− to form from chloro-precursors was rationalized in terms of Gibbs free energies, which were found by ab initio calculations at the CCSD(T)-F12b/aug-cc-pVTZ(-PP)-F12 level of theory to be small or even positive. The work demonstrates that E(CN)6 2− complexes of silicon, germanium and tin are in fact stable at r.t. and exist as well-defined units in the presence of non-coordinating counter-ions. The results add to our understanding of the chemistry of pseudohalogens and structure and bonding.

The interaction of potassium dicyanoaurate and dicyanoargentate with organyltriphenylphosphonium chlorides in water leads to complexes [PH3PH2CN]+[Au(CN)2]– (1) and [PH3PH2PH]+[Ag (CN)2] (2), which and structurally characterized. The phosphorus atoms in organyltriphenylphosphonium cations have a distorted tetrahedral coordination: the CPC angles equal 106.21(17)–111.02(16)° (1), 106.13(7)–111.06(7)° (2), The P-C bonds are 1.782(3)–1.818(3) Å (1) and 1.7985(16)–1.8064(16) Å (2). In the almost linear [Au(CN)2]− anions the CAuC angles are 178.10(19)° (1), the Au-C distances are 1.976(5) and 1.989(5) Å. Similar values in the [Ag(CN)2]– anions are equal to 178.29(8)° and 2.081(3), 2.089 (3) Å, respectively.

“…11 However, quaternary phosphorus salts were seldom utilized as templates in haloargentate system, and only limited haloargentate/quaternary phosphorus hybrids were reported. [12][13][14] The hybridization of alkyl(triphenyl)phosphonium with halometallate will be a good strategy for the development of multifunctional material. 15 First, the tetrahedral geometry of alkyl(triphenyl)phosphonium cations limits benzenebenzene π−π stacking interactions in the lattice; consequently, long persistence phosphors might be achieved.…”

Background: The realization of multifunction in one bulk material is fascinating for developing a new generation of devices. Quaternary phosphorus salts were seldom utilized as templates in haloargentate systems, and the hybridization of alkyl(triphenyl)phosphonium with halometallate will be a good strategy for the development of multifunctional material, especially for biological material. Methods: Under the template of (triphenyl)phosphonium-based quaternary phosphorus salts with different spacer lengths (n=2, 3, 4), three bromoargentate hybrids were constructed via the solution method, ie, (1,2-DBTPP)(Ag 2 Br 4) (1), {(1,3-DBTPP) 2 (Ag 7 Br 11)]•CH 3 CN•H 2 O} n (2), and {[(1,4-DBTPP)(Ag 5 Br 7)](CH 3 CN) 2 •H 2 O} n (3) (1,2-DBTPP 2+ =ethane-1,2-diylbis (triphenyl)phosphonium, 1,3-DBTPP 2+ =propane-1,3-diylbis (triphenyl)phosphonium, 1,4-DBTPP 2 + =butane-1,4-diylbis (triphenyl)phosphonium)). Results: The (Ag 7 Br 11) n 4nchain in 2 is a new type of 1-D bromoargentate chain constructed from cubane-like Ag 4 Br 4 nodes, AgBr 4 tetrahedrons and AgBr 3 triangles. Interestingly, by elongating spacer n from 2 to 4, argentophilicity interactions are weakened, and the hydrogen bonds are strengthened. Consequently, their water stabilities and photocurrents are improved, in which the Ag-4d/Br-4p to π* anti-bonding orbital of the quaternary phosphorus transfer is facilitated. Furthermore, the greenish blue emissions can be detected. Finally, high inhabitation rates against Streptococcus mutans and Candida albicans can be observed in 2 and 3. Conclusion: In all experiments, by elongating the spacer lengths of quaternary phosphorus salts, multifunctions were integrated in the quaternary phosphorus/bromoargentate hybrids, including greenish blue luminescence, repeatable photocurrent responses and durable antimicrobial activities with enhanced water stability. This work could provide a theoretical guide for the design of new biologically multifunctional materials.
