An offer by MacKenzie Capital Management LLC to buy 170 units from the owners of the Empire State Building has largely fizzled, according to regulatory documents filed yesterday.

MacKenzie made the offer of $110,000 per unit to investors in Empire State Building Associates LLC in December.

By the Feb. 8 deadline, MacKenzie had acquired only 13.83 units, according to the filing. There are 3,300 units in total.

MacKenzie, based in Moraga, Calif., offered to buy the units on behalf of funds it manages.
