      The cover picture shows the coupling of an alkyne and [3]cumulene on a zirconium atom to form a seven-membered metallacycloalkyne and a five-membered metallacyclic complex. The reaction is reminiscent of an imaginary Chinese creature, The Black Tortoise (Xuanwu; “Genbu” in Japanese), in which a snake coils around a tortoise. Both the tortoise and the snake are looking at a sphere, which represents a zirconium atom, in a way similar to how the alkyne and the [3]cumulene interact with the metal. The background shows the sunrise at New Year taken from the ruins of Ichiya Castle at Odawara. Details are discussed in the article by N. Suzuki et al. on p. 347 ff.

      It is interesting that replacing one carbon atom with zirconium makes the cycloalkyne so stable...

      Synthesis and Structure of Seven-Membered Metallacycloalkynes (pages 347–356)

      Noriyuki Suzuki, Takashi Tsuchiya, Naoto Aihara, Masakazu Iwasaki, Masahiko Saburi, Teiji Chihara and Yoshiro Masuyama

      Version of Record online: 19 DEC 2012 | DOI: 10.1002/ejic.201201245

      Seven-membered metallacycloalkyne compounds were synthesized and structurally characterized. Zirconocene–alkyne complexes, such as those of 1-(trimethylsilyl)prop-1-yne and diphenylacetylene reacted with [3]cumulene to give 1-zirconacyclohept-2-en-5-yne in good yields. Coupling of benzyne and [3]cumulenes on the metal also gave the corresponding metallacycles.

      Thumbnail image of graphical abstract

      The extent of tilting of YO8/EuO8 polyhedra in Y2Sn2O7 nanoparticles decreases with increasing annealing temperature and this is reflected in the values of the luminescence parameters Ω2 and Ω4, which are related to the extent of polarization in Y–O and Eu–O bonds in the Y2Sn2O7:Eu lattice.

      Three PbII multinuclear complexes were synthesized that show di-, di-, and tetranuclear structures, respectively. A study of the stability of the three complexes demonstrates that they have high thermal stability and extraordinary chemical stability. More importantly, complex 1 shows remarkable acid and alkali resistance.
