    abstract = "A new Cu2+ complex that was isolated from the initial use of
5-((pyridin-4-ylmethylene) amino) isophthalic acid (PEIPH2) in 3d
metal-organic framework (MOF) chemistry is reported. Complex
[Cu-3(PEIP)(2)(5-NH2-mBDC)(DMF)].7DMF8 denoted as Cu-PEIP.7DMF was
isolated from the reaction of Cu(NO3)(2).2.5H(2)O with PEIPH2 in N,
N-dimethylformamide (DMF) at 100 degrees C and contains both the
PEIP2-ligand and its 5-NH2-mBDC(2)-fragment. After the structure and
properties of Cu-PEIP were known an analogous complex was prepared by a
rational synthetic method that involved the reaction of
Cu(NO3)(2).2.5H(2)O, 5-((pyridin-4-ylmethyl) amino) isophthalic acid
(PIPH2 - the reduced analogue of PEIPH2) and 5-NH2-mBDCH(2) in DMF at
100 degrees C. Cu-PEIP comprises two paddle-wheel [Cu-2(COO)(4)] units
and exhibits a 3D-framework with a unique trinodal underlying network
and point symbol (4.52)(4)(4(2).5(4).6(4).8(3).9(2))(2)(5(2).8(4)). This
network consists of pillared kgm-a layers containing a hexagonal shaped
cavity with a relatively large diameter of similar to 8-9 angstrom
surrounded by six trigonal shaped ones with a smaller diameter of
similar to 4-5 angstrom and thus resembles the structure of HKUST-1. Gas
sorption studies revealed that Cu-PEIP exhibits a 1785 m(2) g(-1) BET
area as well as high CO2 sorption capacity (4.75 mmol g(-1) at 273 K)
and CO2/CH4 selectivity (8.5 at zero coverage and 273 K)."
