Summary of main observation and conclusion A series of dicarbene‐bridged metallacycles [Ag2(1)2](PF6)2, [Ag2(2)2](BF4)2, [Ag2(3)2](PF6)2, [Ag2(7)2](BF4)2, [Ag2(8)2](BF4)2 and [Ag2(11)2](PF6)2 were obtained in high yields via the reactions of 1,2,4‐triazole‐, 1,2,3‐triazole‐ and imidazo[1,5‐a]pyridine‐based ligands with Ag2O in CH3CN. The C=C double bonds in all of the newly synthesized metallacycles went through [2 + 2] photodimerization under UV irradiation condition (λ = 365 nm, T = 298 K) yielding the dinuclear rctt‐cyclobutane‐silver(I) complexes [Ag2(4)](PF6)2, [Ag2(5)](BF4)2, [Ag2(6)](PF6)2, [Ag2(9)](BF4)2, [Ag2(10)](BF4)2 and [Ag2(12)](PF6)2, respectively with quantitative yields. Treatment of the these cyclobutane‐bridged silver(I) complexes with NH4Cl resulted in the exclusive formation of cyclobutane derivatives after removal of the silver(I) metal ions.

The love story of “Niu Lang and Zhi Nv” is one of the most famous tales in China. The couple separated by the Tianhe river were able to meet each other once a year with the help of numerous magpies who built a colorful bridge across the river. With this backdrop, Y.‐F. Han et al. present in their article a metal‐carbene‐templated photochemistry in solution. Assisted by the bridge of carbene‐metal‐carbene units, two olefin substrates can reach each other closely, leading to photodimerization and the formation of cyclobutane derivatives. More details are discussed in the article by Han et al. on page 1147–1152.
