A polytype 1T is a single layer trigonal polytype, not a tetragonal polytype, see Guinier et al. Acta Crystallographica (1984) A40, 399-404 "Nomenclature of Polytype Structures".
The English Wikipedia entry on MoS2 is wrong at that point.
In a question like this you should reference the literature at which you found a hint on your material. 1T-MoS2 was described in Wypych & Schöllhorn J, Chem Soc Chem Commun, 1992, 1386-1388.
The paper describes 1T with hexagonal lattice parameters a=5.597 Ang, c=5.994 Ang and the relationship to the standard 2H structure as:
a(1T) = a(2H) SQRT(3)
c(1T) = 1/2C(2H)
No coordinates are listed in the paper, yet a straightforward unit cell translation from 2H to 1T will give you those. A Program like Vesta can be used to calculate the powder diffraction pattern
