Patent ID: 8034165

Claim:
An organic carboxylic acid complex produced by a method for one-dimensionally aligning metal atoms in a single line, said method comprising absorbing a metal vapor with an organic carboxylic acid metal complex constituted by recurring units of the Formula [I]: wherein M 1 and M 2 are each independently a metal which can be bivalent; R 1a , R 1b , R 1c and R 1d are each independently an organic group having a conjugated system; R 2 , R 3 , R 4 and R 5 are each independently hydrogen, C 1 -C 4 alkyl or C 1 -C 4 alkenyl, said organic carboxylic acid complex harboring in a channel structure metal atoms as a guest, said metal atoms being aligned one-dimensionally in a single line.
