NIR-II Emission from Cyclometalated Dinuclear Pt(III) Complexes.

ABSTRACT: Half-lantern Pt(II) dinuclear complexes [{Pt(C^∧N_pz)(μ-S^∧N^R)}₂] (HC^∧N_pz = 1-naphthalen-2-yl-1H-pyrazole; R = H, HS^∧N: 2-mercaptopyrimidine 1; R = CF₃, HS^∧N^F: 4-(trifluoromethyl)-2-mercaptopyrimidine 2) were selectively obtained as single isomers with the C^∧N groups in an anti-arrangement and rather short metallophilic interactions (d_Pt-Pt = 2.8684(2) Å for 2). They reacted with haloforms in the air and sunlight to obtain the corresponding oxidized diplatinum(III) derivatives [{Pt(C^∧N_pz)(μ-S^∧N^R)X}₂] (X = Cl (1-Cl), Br (1-Br), I (1-I, <
