formation of metal–organic frameworks (MOFs)
is an emerging field, where each new discovery propels the field forward.
Often, studies focus on studying nucleation events with advanced spectroscopy
and microscopy techniques. Efforts to synthetically understand the
molecular intermediates involved and their role in self-assembly are
less common. Herein we report the synthesis of a MOF, YCM-41 (YCM = Youngstown Crystalline Material), that contains two different
In-nodes: one the standard [In(CO2R)4]− and the second of [In(CO2R)3Cl]−. We hypothesize that the [In(CO2R)3Cl]− is a mechanistic intermediate in the synthesis of
[In(CO2R)4]−. Additionally,
we report the isolation of 1-D coordination polymer, YCM-42, containing the previously unreported [In(CO2R)2Cl2]− building unit. The 1-D herringbone
structure of YCM-42 can be found in YCM-41. Finally, attempts to synthesize
an isoreticular version of these structures led to the synthesis of
the 1-D coordination polymer YCM-51, which contains a
[In(CO2R)2Cl2F]2– center.
