We present high-resolution 6-cm continuum observations of the molecular cloud G35.2 - 0.74. Two sources associated with the cloud were detected, one of which (G35.2S) is a near-symmetric H II region with a diameter of ~0.37 pc. It is thought that a stellar wind, rather than pressure expansion of the H II region, could be responsible for the unusual 3-km s-1 molecular line-splitting observed around this object. The second continuum source (G35.2N) has a double-peaked structure, with an orientation very close to that of the surrounding dense elongated molecular cloud. A model which might explain both the structure of G35.2N and the detection of bipolar outflow in HCO+ (Matthews et al. 1984) is that of a disk-constrained outflow, as proposed for S106 by Bally and Scoville 1982.
