摘要：

Organocesium compounds, which are still a rarity, are easily prepared using a droplet of liquid cesium and occasional ultrasonic surface reactivation. Despite their extreme air sensitivity, structure analysis has been achieved under a cooled-N-2 flow both for the black coordination polymer (tetraphenylethanediyl)dicesium bis(diglyme) ([(Ph(2)C-CPh(2))(2-)(Cs+(diglyme)(2)](infinity)), which exhibits the expected cyanine distortion with the molecular halves C--(C6H5)(2) twisted by 76 degrees around the central CC single bond of 1.51 Angstrom length, and for the violet-blue coordination polymer (1,1,4,4- tetraphenyl-butadiene-2,3-diyl)tetracesium bis(diglyme) bis(2-methoxyethanolate) ([(Ph(2)C=(CHCH)=CPh(2))(2-)(Cs+(diglyme))-(Cs+-OCH2CH2OCH3)(2)](infinity)), which shows a bond alternancy change relative to the hydrocarbon, >C=C(H)-(H)C=C<+ 2e(-) --> >C--C(H)=(H)C-C--<.
