Narrative:
Air carrier X departed ind. I left on initial heading to climb and avoid traffic. When air carrier X was clear of traffic, I turned on course to djb and climbed to FL310. I then flashed to sector 98-super high. I was done with this aircraft other than to switch to super-high after handoff taken. I then began to look for a NORDO aircraft in my sector. My radar associate coordinated a pointout on air carrier X climbing to FL330 eastbound. Controller told me to climb air carrier X to FL330. I did climb air carrier X to FL330. Leaving FL310, the conflict alert began to flash with an air carrier Y at FL330, sebound. The vector lines were 2 mins apart. I immediately turned air carrier X 25 degrees left to avoid the imminent situation and then told radar associate to coordinate turn with super high sector (98). The turn was not coordinated and air carrier Y got within 4.2 mi horizontal with air carrier X.

Title: ZID RADAR AND ASSOCIATE CTLR'S MISCOORD RESULTS IN A CONFLICT BTWN A CLBING DC10 CONFLICTING WITH AN ENRTE DC9.
Narrative: ACR X DEPARTED IND. I LEFT ON INITIAL HEADING TO CLB AND AVOID TFC. WHEN ACR X WAS CLR OF TFC, I TURNED ON COURSE TO DJB AND CLBED TO FL310. I THEN FLASHED TO SECTOR 98-SUPER HIGH. I WAS DONE WITH THIS ACFT OTHER THAN TO SWITCH TO SUPER-HIGH AFTER HDOF TAKEN. I THEN BEGAN TO LOOK FOR A NORDO ACFT IN MY SECTOR. MY RADAR ASSOCIATE COORDINATED A POINTOUT ON ACR X CLBING TO FL330 EBOUND. CTLR TOLD ME TO CLB ACR X TO FL330. I DID CLB ACR X TO FL330. LEAVING FL310, THE CONFLICT ALERT BEGAN TO FLASH WITH AN ACR Y AT FL330, SEBOUND. THE VECTOR LINES WERE 2 MINS APART. I IMMEDIATELY TURNED ACR X 25 DEGS L TO AVOID THE IMMINENT SIT AND THEN TOLD RADAR ASSOCIATE TO COORDINATE TURN WITH SUPER HIGH SECTOR (98). THE TURN WAS NOT COORDINATED AND ACR Y GOT WITHIN 4.2 MI HORIZONTAL WITH ACR X.
