“…The platinum coordination planes are almost parallel (interplanar angle 9.5(1)8) [82] and staggered with a torsion angle N(3)-Pt(1)-Pt(2)-N(7) of 31.58 appropriate to a local h 2 and s (N, dmpz) dicoordination of the Cu centers. All Cu atoms adopt a linear coordination with similar geometric environments, formed by the N atom and the midpoint of the coordinated CC vector (C 0 ), as the N-Cu-C 0 angles are 169.28 (Cu (1) [25,[83][84][85][86][87][88][89][90][91] As far as we know, a small number of Cu I complexes with an L-CuA C H T U N G T R E N N U N G (h 2 -C CR) coordination environment have been reported. [83][84][85] The CuÀN and PtÀN bond lengths are in the range of those found in pyrazolato copper(i) [36-42, 56, 57, 63, 92] and Pt II complexes.…”

This work describes the synthesis of cis-[Pt(C[triple bond]CPh)2(Hdmpz)2] (1) and its use as a precursor for the preparation of homo- and heteropolynuclear complexes. Double deprotonation of compound 1 with readily available M(I) (M = Cu, Ag, Au) or M(II) (M = Pd, Pt) species affords the discrete hexanuclear clusters [{PtM2(mu-C[triple bond]CPh)2(mu-dmpz)(2)}(2)] [M = Cu (2), Ag (3), Au (4)], in which both "Pt(C[triple bond]CPh)2(dmpz)(2)" fragments are connected by four d(10) metal centers, and are stabilized by alkynyl and dimethylpyrazolate bridging ligands, or the trinuclear complexes [Pt(mu-C[triple bond]CPh)2(mu-dmpz)(2){M(C/\P)}2] (M = Pd (5), Pt (6); C/\P = CH(2)-C(6)H(4)-P(o-tolyl)2-kappaC,P), respectively. The X-ray structures of complexes 1-4 and 6 are reported. The X-ray structure of the platinum-copper derivative 2 shows that all copper centers exhibit similar local geometry being linearly coordinated to a nitrogen atom and eta(2) to one alkynyl fragment. However in the related platinum-silver (3) and platinum-gold (4) derivatives the silver and gold atoms present three different coordination environments. The complexes have been studied by absorption and emission spectroscopy. The hexanuclear complexes exhibit bright luminescence in the solid state and in fluid solution (except 4 in the solid state at 298 K). Dual long-lived emission is observed, being clearly resolved in low-temperature rigid media. The low-energy emission is ascribed to MLM'CT Pt(d)/pi(C[triple bond]CPh)-->Pt(p(z))/M'(sp)/pi*(C[triple bond]CPh) modified by metal-metal interactions whereas the high-energy emission is tentatively attributed to an emissive state derived from dimethylpyrazolate-to-metal (d(10)) LM'CT transitions pi(dmpz)-->M'(d(10)).

The unexpected finding that the complex [Au(PPh3)2]PF6 (C1) catalyses the specific hydration of 1‐octyne, (p‐phenoxyphenyl)acetylene, phenylacetylene, (p‐chlorophenyl)acetylene and benzylacetylene at 100 °C in the presence of H2SO4 and THF or methanol as solvents, specially using microwave radiation, led to the first gold(I) recyclable catalysts for this reaction. The phosphazene polymeric framework of idealised formula {[NP(O2C12H8)]0.85[NP(OC6H4PPh2)2 (AuPF6)0.5]0.15}n (C2), and the newly synthesised cyclomatrix material of idealised formula {[N3P3(OC6H4PPh2)6](AuPF6)3.5}n (C3), both having cationic [–Ph2P–Au+–PPh2–] cross‐linking sites, catalysed the complete hydration of terminal alkynes at 100 °C and 150 °C and could be used six and four times respectively without significant loss of activity. The mechanism of the catalytic system is based on the initial reversible displacement of one anchoring O–C6H5–PPh2 group from the [–Ph2P–Au+–PPh2–] cross‐linking sites by an alkyne molecule. Using microwave radiation, the hydration of (p‐phenoxyphenyl)acetylene, phenylacetylene, (p‐chlorophenyl)acetylene and benzylacetylene can be completed in 5 min to 2 h in the absence of any gold(I) catalyst.
