A two-dimensional and bifunctional pillar-layered metal–organic framework (MOF)—with the molecular formula [Zn(cba)(bpdb)]·DMF (2DTMU-1), H2cba = 4,4′-methylenedibenzoic acid, bpdb 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene—was obtained via reaction of zinc(II) nitrate with as carboxylate linker N-donor pillar. 2DTMU-1 is based on a binuclear paddlewheel Zn(II) unit complexed by four bridging b...

two new nano-sized lead(ii) and mercury(ii) coordination polymers, [pb(2-bpdh)(no3)2(h2o)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4-hexadiene)} and [hg(4-bpdb)(scn)2]n (2); (4-bpdb= 1,4-bis(4-pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. the structure of 1 may be considered coordination polymer of lead(ii) and single crystal x–ray analysis of compound 2reve...

Two new nano-sized lead(II) and mercury(II) coordination polymers, [Pb(2-bpdh)(NO3)2(H2O)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza- 2,4-hexadiene)} and [Hg(4-bpdb)(SCN)2]n (2); (4-bpdb= 1,4-bis(4- pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) and Single crystal X–ray analysis of compound ...

Moving pages that are not backed up on real NVRAM to disk-based storage and ensuring that they are accessible will involve at least one I/O, if not more. As a result, the I/O performance of a BPDB that attempts to exploit NVRAM may even be worst than a similar BPDB system that does not do so if the amount of NVRAM available is less than that assumed by the former system. This performance anomal...

A six-coordinated 3D metal–organic framework (MOF), namely, [Co(BPDC)(3-bpdb)(H2O)2]n (1) (H2BPDC = 4,4?-biphenyldicarboxylic acid, 3-bpdb 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene) was purposefully constructed and characterized by single-crystal XRD, IR, elemental analyses, PXRD, SEM, TGA. Crystal structural analysis revealed that the complex consists of a cds-type three-fold interpenetrated ...
