خماسي فلوريد الكلور هو مركب بين هالوجيني مكون الفلور والكلور صيغته ClF5، ويوجد على شكل غاز عديم اللون.

التحضير

يمكن أن يحضر المركب من تفاعل فلورة ثلاثي فلوريد الكلور عند درجات حرارة وضغوط مرتفعة.[2][3]

يمكن أن يستخدم ثنائي فلوريد النيكل حفازاً لهذا التفاعل.[4]

الخواص

يوجد المركب على شكل غاز عديم اللون، وهو يتفاعل مع الماء (تفاعل حلمهة) عند التماس معه مشكلاً فلوريد الكلوريل وفلوريد الهيدروجين:[5]

للمركب بنية جزيئية هرمية مربعة وتناظر جزيئي من النمط C4v؛[5] وفق ما أثبت باستخدام مطيافية الرنين المغناطيسي النووي لنظير الفلور-19 19F NMR.[6]

الاستخدامات

يمكن أن يستخدم المركب لإجراء عمليات الفلورة في تفاعلات الاصطناع العضوي.
