Structure of a copper(I) chloride adduct of a manganese(I) complex

Abstract

Abstract. fac-Tricarbonyl{[Mn(CO)3(dppe)(C=CPh)].CuCl}, where the carboncarbon triple bond of the phenylethynyl moiety acts as a r/2-acetylene ligand coordinated to the Cu ~ atom, which is thereby in a formally two-coordinated complex. The Mn ion displays a distorted octahedral coordination with the two P atoms of the dppe ligand and the two carbonyl groups in the equatorial plane. The steric hindrance produces an enlargement of the equatorial P--Mn--C angles and a reduction of the apical P--Mn-C angles.

Homo‐ and Heteropolynuclear Platinum Complexes Stabilized by Dimethylpyrazolato and Alkynyl Bridging Ligands: Synthesis, Structures, and Luminescence

“…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.…”

[52,53,[73][74][75][76][77][78] As expected [79][80][81] the Pt-C a C b -C Ph units deviate from linearity, this distortion being more pronounced at the C b atom (161.7(6)-167.5 (7)8) and the C a C b bond lengths are slightly elongated with respect to complex 1.…”

σ-Alkynyl complexes of manganese(I) as η2-bonding ligands for Group 1B metal–ligand fragments. X-Ray crystal structure of [Mn2Cu(µ-CCBut)2(CO)6(dppe)2]PF6·0.5CH2Cl2

“…On the other hand the reaction of the o-alkynyls (la) and (lb) with [Au(C,F,)(tht)]* gave the stable compounds [MnAu(C,F,)(y-CCR)(CO),(dppe)] (3a, R = CH,OMe) and (3b, R = But) in which presumably the manganese alkynyl co-ordinates the Au(C,F,) fragment in a side-on fashion. Thus, the v(C0) 89.4 (6) frequencies in the i.r. spectra of complexes (3) are very similar to those of the CuCl species (2) and, although no bands assignable to the v(C2c) vibrations could be observed, these bands could be obscured by the v(C0) absorptions at lower frequencies.…”

“…An occupancy factor of 0.5 was assigned to the disordered atoms, according to the heights of the peaks in the Fourier synthesis; 22 H atoms located from difference synthesis; refined with an overall isotropic temperature factor. Final R 0.054 Table 1" and selected bond lengths and angles in (Solans, Solans, Miratvilles, Miguel, Riera & Rubio-Gonzalez, 1986 [average value 1.823 (5)/k] (Carriedo, Crespo, Riera, Sanchez, Valin, Moreiras & Solans, 1986). The alkynyl moiety is essentially linear with angles C(13)-C(12)-C(11)= 178.0(6) ° and Mn-C(ll)-C(12) = 179.0 (5) °.…”
