We searched for the phi(--)(1860) pentaquark in the photoproduction process off the deuteron in the Xi(-)pi(-)-decay channel using CLAS. The invariant-mass spectrum of the Xi(-)pi(-) system does not indicate any statistically significant enhancement near the reported mass M = 1.860 GeV. The statistical analysis of the sideband-subtracted mass spectrum yields a 90%-confidence-level upper limit of 0.7 nb for the photoproduction cross section of phi(--)(1860) with a consecutive decay into Xi(-)pi(-) in the photon-energy range 4.5 GeV \u3c E-gamma \u3c 5.5 GeV
