Narrative:
My plan was to give the E145 a 290 degree heading and then descend another aircraft (not involved) to FL200. I erroneously gave the E145 a 200 degree heading. Thinking he was paralleling the BE90; I did some radar associate duties. I looked back to the radar to see the E145 on a 200 degree heading closing on the BE90. I then issued the E145 a 240 degree heading. During the incident the E145 was climbing. The BE90 was level at 16000 ft. When I realized the E145 was heading toward the BE90; the E145 was out of 16300 ft. The E145 continued to climb when I issued the 240 degree heading.

Title: ZBW CTLR EXPERIENCED OPERROR AT 16000 FT WHEN ISSUING A CONFLICTING HDG TO A CLBING ACFT THROUGH AN OCCUPIED ALT.
Narrative: MY PLAN WAS TO GIVE THE E145 A 290 DEG HDG AND THEN DSND ANOTHER ACFT (NOT INVOLVED) TO FL200. I ERRONEOUSLY GAVE THE E145 A 200 DEG HDG. THINKING HE WAS PARALLELING THE BE90; I DID SOME RADAR ASSOCIATE DUTIES. I LOOKED BACK TO THE RADAR TO SEE THE E145 ON A 200 DEG HDG CLOSING ON THE BE90. I THEN ISSUED THE E145 A 240 DEG HDG. DURING THE INCIDENT THE E145 WAS CLBING. THE BE90 WAS LEVEL AT 16000 FT. WHEN I REALIZED THE E145 WAS HEADING TOWARD THE BE90; THE E145 WAS OUT OF 16300 FT. THE E145 CONTINUED TO CLB WHEN I ISSUED THE 240 DEG HDG.
