The title compd. is triclinic, space group P.hivin.1, with a 7.832(3), b 9.419(1), c 10.771(1) .ANG., a 85.93(1), b 72.90(2), and g 69.64(3) Deg; d.(calcd.) = 1.075 for Z = 1. Final R = 0.055 for 2025. At. coordinates are given. The structure consists of centrosym. tert-Bu 2-lithiophenyl) sulfide dimers [around (1/200)] which are linked together by bridging centrosym. N,N,N',N'-tetramethylethylenediamine mols. [around (000)] to form 1-dimensional infinite chains. The Li atom has a distorted tetrahedral coordination sphere consisting of 2 C atoms of symmetry-related Ph rings, 1 N atom, and 1 S atom. The Ph ring is distorted in a way which is common for all aryl groups bonded to electropos. elements.
