Narrative:
Citation descended to FL350 from FL390, shipped to me. I descended citation to FL330. Controller realized airbus would be in conflict with another aircraft and turned to avoid, putting in conflict with citation. I turned the citation right 30 degrees when I realized they were in conflict. After clearing citation back on course, citation said 'that's ok. We had him on TCASII and in visual.'
