We observed the X-ray binaries CirX-1, ScoX-1, GRS 1915+105, GX13+1, andCygX-1 with the Atacama Large Millimeter/submillimeter Array (ALMA). Unresolvedcontinuum emission is found at the positions of all the sources at a frequencyof 92 GHz, with flux densities ranging between 0.8 and 10 mJy/beam. In allcases the emission can be associated with jets that have been extensivelyobserved at lower frequencies. We searched for line emission from H$\alpha$recombination, SiO,H2O, and CH3OH at the positions of all the sources and, forCirX-1 and CygX-1, also at regions where shocks associated with an interactionbetween the jet and the interstellar medium had previously been observed. Thesearch did not yield any significant detection, resulting in 3$\sigma$ upperlimits between 0.65 and 3.7 K km s$^{-1}$ for the existence of line emission inthese regions. In contrast, we detected spatially unresolved SiO emission inthe field of view of GX13+1, and we tentatively associate this emission with aSiO maser in a potential young stellar object or evolved star. We also foundspatially extended line emission at two additional sites in the field of viewof GX13+1 that we tentatively associate with emission from SO and CH3OH; wespeculate that it may be associated with a star-forming region, but again wecannot rule out alternative origins such as emission from evolved stars.
