The mass, coupling and width of the newly observed charged resonance Z(c)(-)(4100) are calculated by treating it as a scalar four-quark system with a diquark-antidiquark structure. The mass and coupling of the state Z(c)(-)(4100) are calculated using the QCD two-point sum rules. In these calculations we take into account contributions of the quark, gluon and mixed condensates up to dimension ten. The spectroscopic parameters of Z(c)(-)(4100) obtained by this way are employed to study its S-wave decays to c(1S)-, c(2S)-, D0D-, and J/- final states. To this end, we evaluate the strong coupling constants corresponding to the vertices Zcc(1S)-, Zcc(2S)-, ZcD0D-, and ZcJ/- respectively. The couplings gZcc1, gZcc2, and gZcDD are computed by means of the QCD three-point sum rule method, whereas gZcJ/ is obtained from the QCD light-cone sum rule approach and soft-meson approximation. Our results for the mass m=(4080 +/- 150)MeV and total width =(147 +/- 19)MeV of the resonance Z(c)(-)(4100) are in excellent agreement with the existing LHCb data.
