High-resolution radio observations of L1689N, a dense molecular core in the Rho Oph molecular complex, are reported. Transitions of (C-12)O, (C-13)O, C(O-18), DCO(+), H(C-13)O(+), SO, and NH3 were mapped during 1984-1986 using the 4.9-m antenna at the Millimeter Wave Observatory, the 43-m antenna at NRAO Green Bank, the VLA, and the 12-m NRAO telescope at KPNO; the results are presented graphically and characterized in detail. Most of the dense material in L1689N is found to be contained in a gravitationally bound cold clump with mass about 20 solar masses and maximum density n(H2) = about 10 to the 6th/cu cm. A warmed clump, lying 0.07 pc west of the cold clump and surrounding IRAS 16293-422, is found to contain a bipolar mass-outflow region with crossing time about 9000 yr. 33 references.
