Tricarbonyltris(pyridine)molybdenum(0) is a yellow to orange crystalline compound that can be handled in the ambient atmosphere without noticeable decomposition. It can be stored indefinitely at 0-5°C under an inert atmosphere. It decomposes at 205-210°C (a gradual change in color from yellow to brown is already observed starting at 100-105°C). Its IR spectrum shows two carbonyl bands at 1901 and 1764 cm.  

DICARBONYL HYDRIDOTRIS(l-PYRAZOLYL)BORATO i/-(l,2,3)-( + )-(lR,2R)-l-(METHOXYCARBONYL)-2-PROPEN-l-YL MOLYBDENUM(II), Mo(CO)2(i/ -CH2CH=CHC02CH3)Tp 

Checkers used nitrogen atmosphere througjiout instead of argon. Checkers used high purity pyridine (Aldrich) without further purification.
